A Secure Chat App’s Encryption Is So Bad It Is ‘Meaningless’


A Secure Chat App’s Encryption Is So Bad It Is ‘Meaningless’

TeleGuard, an app that markets itself as a secure, end-to-end encrypted messaging platform which has been downloaded more than a million times, implements its encryption so poorly that an attacker can trivially access a user’s private key and decrypt their messages, multiple security researchers told 404 Media. TeleGuard also uploads users’ private keys to a company server, meaning TeleGuard itself could decrypt its users’ messages, and the key can also at least partially be derived from simply intercepting a user’s traffic, the researchers found.

The news highlights something of the wild west of encrypted messaging apps, where not all are created equal.

“No storage of data. Highly encrypted. Swiss made,” the website for TeleGuard reads. The site also says, “The chats as well as voice and video calls are end-to-end encrypted.”

💡
Do you know anything else about this app or other security issues? I would love to hear from you. Using a non-work device, you can message me securely on Signal at joseph.404 or send me an email at joseph@404media.co.

In March an anonymous security researcher, who didn’t provide their name, told 404 Media about a series of vulnerabilities in TeleGuard. They included the fact the TeleGuard app uploads users’ private encryption keys to the company’s server upon account registration. 

Often when implementing encrypted messages, apps will assign users a public and private key. The public key is what other users use to encrypt messages for them, and the private key is what a user uses to decrypt messages meant for them. If this key falls into someone else’s hands, they may be able to read a users’ messages.

In true end-to-end encryption, this encryption happens on a user’s phone, and the key should never leave that device. With TeleGuard, the app is transmitting that highly sensitive key to the company’s servers. Technically, the app uploads an encrypted version of the private key, but it also transmits other information that allows the server to decrypt it, the researcher explained. That includes the user’s unique ID, which is also uploaded along with the key; a hardcoded salt (which in cryptography is supposed to be a random string of characters, but in this case is constant); and a hardcoded nonce (which is also supposed to be random for every communication to stop certain attacks, but is constant with TeleGuard). “The server can decrypt every user’s private key. It has everything,” the researcher wrote in their findings shared with 404 Media.



That series of design decisions means TeleGuard, the company, receives users’ private keys. But the keys are also accessible to other attackers. The researcher found it’s possible to retrieve a specific user’s private key by simply plugging their user ID into TeleGuard’s API. Many people share their user ID publicly so they can be contacted, opening them up to this attack.

404 Media asked Dan Guido, CEO and co-founder of cybersecurity firm Trail of Bits, whether his team was able to verify the findings. Guido said the company found much the same thing, and added the app’s encryption “is meaningless,” because of the app uploading the private keys and the server’s ability to decrypt them.

Trail of Bits then found multiple other security issues with TeleGuard, including being able to at least partially extract users’ private keys from simply intercepting their traffic. Trail of Bits said it then successfully decrypted one of the shoddily encrypted private keys from that capture.

Guido sent 404 Media this meme:

The researcher who initially reached out also said TeleGuard’s metadata—when someone sent a message, and to whom—is in plaintext, meaning that could be exposed to attackers too.

TeleGuard launched in around 2021, according to archives of the app’s page on the Wayback Machine. It is made by Swisscows, a company that also makes what it describes as an anonymous search engine, a VPN, and an email service. In a promotional video, TeleGuard claims to have “one of the strongest encryptions available.”

Neither TeleGuard nor Swisscows responded to multiple requests for comment, nor gave any indication or timeline of when they might fix the issues. 

TeleGuard has been recommended to cam models as a way to communicate, according to a post on a  subreddit for models. The app has also repeatedly been linked to child abusers, with one local media outlet reporting TeleGuard is “notorious” among prosecutors for child sexual abuse material. The FBI previously obtained data about a TeleGuard user through push notifications sent to their phone. A foreign law enforcement agency had TeleGuard hand over push notification-related data, which the FBI then took to Google to obtain email addresses linked to that alleged pedophile, The Washington Post reported.

Artemis II Astronauts Have ‘Two Microsoft Outlooks’ and Neither Work


Artemis II Astronauts Have ‘Two Microsoft Outlooks’ and Neither Work

In 1969, the three astronauts of the Apollo 10 mission conducted a momentous “dress rehearsal” for putting humans on the lunar surface for the first time. It was a historic, inspiring moment for humanity; Astronaut John Young watched from a command module spacecraft as Thomas Stafford and Gene Cernan broke away and flew a lunar module within 10 miles of the moon’s surface, then reunited to return home to Earth. It’s from this mission that we have one of the most powerful transcripts in NASA history: 

“Who did what?” Young asked. “Where did that come from?” Cernan added.

“Give me a napkin quick,” Stafford said. “There’s a turd floating through the air.”

The provenance of the poop remains one of the great mysteries of spaceflight. Today, in the early Earth-morning hours of the Artemis II astronauts’ history-mirroring mission around the moon, we have another: Why is Microsoft Outlook not working in space? 

On April 1, four astronauts from the U.S. and Canada embarked on a 10-day flight to loop around the moon. Spotted by VGBees podcast host Niki Grayson on the NASA livestream of live views from the , around 2 a.m. ET, Kennedy Space Center mission control acknowledges an issue with a process control system and offers to remote in—yes, like how your office IT guy would pause his CoD campaign to log into Okta for you because you used the wrong password too many times.

One of the astronauts, Reid Wiseman, says that’s chill, but while they’re in there: “I also see that I have two Microsoft Outlooks, and neither one of those are working.” 

right now the astronauts are calling houston because the computer on the spaceship is running two instances of microsoft outlook and they can’t figure out why. nasa is about to remote into the computer

Astronauts are trained for decades in some of the most physically and mentally grueling environments of any career. They’re some of the smartest people on the planet, and they have to be, before we strap them to 3.2 million pounds of jet fuel and make them do complex experiments and high-stakes decisions for days on end. And yet, once they get up there, fucking Outlook is borked. 

I scanned through the next several minutes after this moment and didn’t hear them address the duplicate Outlooks again. So, I emailed the Artemis II communications team, who is definitely not busy today I’m sure, and asked: Can the astronauts check their email yet?

I’ll update if I hear back.

‘You Can’t Defeat the Robots!’: Baseball’s AI Strike Zone Is Must-Watch Television


'You Can't Defeat the Robots!': Baseball's AI Strike Zone Is Must-Watch Television

With the bases loaded and two outs in the top of the seventh inning of Sunday’s Twins-Orioles game, Twins cleanup hitter Matt Wallner watched a knee-high 3-2 pitch sail directly over the heart of the plate for strike three. Rather than accept his fate, an emotional, frustrated Wallner tapped his helmet, signaling that he was challenging an obvious strike under Major League Baseball’s new automated ball-strike challenge system. Baseball’s new AI-powered strike zone robots confirmed the call on the field, and the Twins lost the ability to challenge for the rest of the game. This very human, very emotion-driven mistake then set up a series of events resulting in the first ever manager ejection for arguing about a robot’s decision, perhaps a glimpse at the future of baseball and, if you squint, a microcosm of various human-AI beefs in society more broadly. 

We are four days into the new baseball season, and this season’s brand new Automated Ball-Strike (ABS) system is the dominant storyline so far. Here’s how the system works, more or less: Like usual, a human umpire calls each pitch a ball or a strike. Immediately following that call, the pitcher, catcher, or batter can challenge the call by tapping on their head. The location of the pitch is then immediately shown on the stadium’s scoreboard on a graphic that includes each hitter’s strike zone; if the ball is within or clips any part of the strike zone box, it’s a strike. If not, it’s a ball. This all happens in a matter of seconds automatically on the Jumbotron and is driven by AI; its results are inarguable. There is no long human review process in a video booth in New York like there is for other umpire’s challenges. 

And yet, the ABS system feels somehow extremely human, because human beings are making the decisions on what to challenge, under what circumstances, and how to react to any given decision. ABS is also not exactly human vs robot, it is a human player’s judgment vs a human umpire’s judgment as adjudicated by an AI system, which has made it must-watch television. Anyone who has screamed “that was a strike” at their TV now gets the satisfaction of having a player’s apparently superior judgment have actual consequences in the game. And, because the home TV broadcasts have a strikezone superimposed on the proceedings, watching from home means you can, in real time, think “they should challenge that,” or “dumb challenge.” 

How Thomson Reuters Powers ICE and Palantir


How Thomson Reuters Powers ICE and Palantir

Thomson Reuters, the media company which is also a data broker, has long provided underlying personal data for Immigration and Customs Enforcement (ICE) tools, according to documents obtained by 404 Media and sources. There are also indications its data is now part of the Palantir system ICE uses to find which neighborhoods to target.

The findings draw a clearer line between Thomson Reuters’ data business—which can involve selling names, addresses, car registration information, Social Security numbers, and details on someone’s ethnicity under the brand name CLEAR—and the specific tools ICE is ingesting the data into. The news also comes after Thomson Reuters employees sent leadership a signed letter expressing their unease with the company’s ICE and Department of Homeland Security (DHS) contracts, the Minnesota Star Tribune reported last month.

“If these allegations are true, they cut directly against Thomson Reuters’ claims that its products and services are limited to fighting serious crime and are not facilitating deportations,” Emma Pullman, head of shareholder engagement and responsible investment for the B.C. General Employees’ Union (BCGEU), told 404 Media. BCGEU is a minority shareholder in Thomson Reuters and has recently engaged the company concerning its work with ICE, BCGEU said.

Iran Is Winning the AI Slop Propaganda War


Iran Is Winning the AI Slop Propaganda War

An AI-generated LEGO movie out of Iran depicting Trump as a war hungry pedophile has gone viral online. The video is the work of Iran-based propagandists called the “Explosive News Team” and is just the latest in a long line of AI-generated LEGO videos aimed at mocking Trump and Benjamin Netanyahu. LEGO-themed propaganda isn’t new and the Iranian video plays on familiar wartime propaganda themes. What’s different in 2026 is speed and scale.

During World War II, the Korean War, and the Vietnam War, America’s enemies littered the battlefield with pamphlets, cartoons, and radio broadcasts aimed at shaking the morale of American troops, but that stuff rarely got back home. Now, Iran can use AI tools to produce lavishly animated cartoons at scale for dissemination across social media all aimed at the US homefront.



The latest “Explosive News Team” video is set to a catchy rap song about how Trump is a LOSER and millions of people are watching it across multiple platforms. At the same time Iran is releasing AI-generated videos of Trump drowning in a river of blood, the US Department of Homeland Security is sharing fashwave filtered pictures of Gen Z ICE agents milling around airports.

Iran’s use of LEGO set rap music tells me it’s been studying us. These are videos meant for the American people crafted in a language Iran knows we’ll understand. 

Meanwhile, the White House is dropping Grand Theft Auto and Call of Duty memes that were out of fashion 10 years ago on Reddit and vague-posting pixelated images of Trump like it’s running an ARG. Iran is attempting to speak to the broader American public. Trump is confident he only has to impress the online freaks he thinks still love him.

In other words, there’s a AI slopaganda proxy war playing out, and Trump is speaking only to people whose brains are rotting out of their skull, while Iranian  propaganda is currently doing a better job of speaking to the concerns of the broad American population than the American president. Trump continues to narrowcast to his base while losing support for his wildly unpopular war as Americans worry about skyrocketing gas prices, a tanking economy and stock market, insane lines at airports, and a war that has little rationale and apparently no real goal. A recent Pew poll found 61 percent of Americans disapprove of Trump’s handling of the conflict. 

To be clear, it speaks to how bad things are online that we need to analyze whose AI disinformation and propaganda is “better,” and, in general, the slopification of the internet has been a disaster. And yet, the stuff Iran is making is resonating and spreading online in a way that Trump’s slop is not. We do not know who, specifically, is making the Iranian AI slop or which tools they are using to make it. But the fact that Iranian AI slop is resonating with Americans while American slop is not should perhaps not be surprising; for the last several years, the most successful purveyors of AI slop have largely been based in foreign countries, where they have been incentivized to make content that specifically targets American audiences because of the way that social media ad rates work. Because of that, an entire economy has emerged in which people who would otherwise have little interest in reaching American audiences have been incentivized to study what resonates with Americans on the internet and have created entire businesses focused on teaching other people what Americans care about and how to target them with AI slop.  


Propaganda, especially war-time propaganda, is about causing a quick emotional reaction in the viewer. Iran has proved remarkably capable of that and hits similar themes in most of its videos: Epstein, Netanyahu, and blood. “The really striking throughline is the 1) connecting victims from Minab to Epstein, 2) a cartoonish antisemitism that attributes the bog-standard reactionary hawkishness of Trump and Netanyahu to a sinister and supernatural evil, 3) heavy emphasis on missiles and revenge-weapons,” Kelsey Atherton, Chief Editor at Center for International Policy, told 404 Media.

“There’s a grand tradition of wartime propaganda aimed at convincing the other side to quit and I think Iran’s best falls into that camp, like North Korea and especially North Vietnam sending pamphlets aimed at getting black soldiers to defect by highlighting inequity at home,” Atherton said. “Iran’s online propaganda is trying to activate this by (charitably) appealing to class war and (uncharitably) leaning on antisemitism to get US soldiers to quit and to erode support among Americans watching short-form vertical video.”

In one AI-generated video shared by Russian state controlled news organization RT depicts victims of American military campaigns staring at the sky. It begins with an American Indian then cuts to a boy in Hiroshima, a schoolgirl in Minab, a little girl in front of the bizarre temple on Epstein’s Island, and ends with US-assassinated Quds Forces leader Qasem Soleimani.

US Under Secretary of State Sarah B Rogers attempted to critique the video in a post on X. “You do see common propaganda threads here and elsewhere: the ideology is resentment-driven, civilization-skeptical, and obsessed with upending, cathartic violence enacted by the ‘historically downtrodden’ (ie ‘wretched of the earth’),” she said

The post felt like projection and was especially strange given the Trump administration’s own resentment driven ideology, destruction of institutions, and obsession with revenge-driven violence on behalf of the “forgotten man.” Iran did not start America’s war with it. And it did not start the AI-generated propaganda war, it’s just doing it better than the United States.

There are other echoes of the past. An AI-generated Iranian riff on Pixar’s Inside Out shared on X by Iran’s embassy in the Hague showed a Disneyesque version of the inside of Trump’s brain. It showed frothing demons demanding the President lie to the press. A poster from World War II depicts an X-Ray photo of Hitler’s Brain filled with skeletons and snakes. It’s the same theme in different eras using different tools.

LEGO bricks, too, are a far older propaganda tool than the current war. The Danish bricks are one of the most recognizable toys on the planet. Last year, Russian propagandists circulated images of fake LEGO sets depicting soldier’s funerals ahead of an election in Moldova. In 2020, the Chinese released “Once Upon a Virus,” a LEGO short film that mocked America’s response to the Covid pandemic.

The Trump administration’s new fascist aesthetic is defined by AI slop. From Studio Ghibli-inspired grotesques to AI-generated Sora videos of ICE raids that never happened going viral on Facebook, Trump and his supporters are also using the tools of the moment to churn out crappy propaganda. The difference is that Trump’s videos aren’t about winning hearts and minds, they’re about activating a rapidly diminishing base of supporters.

“I think Trump’s stuff is aimed at the same audience, except to convince them that what they’re doing is righteous and good,” Atherton said. “Obviously we’re seeing the stuff put out in English to English video-watching audiences but White House videos—AI or otherwise—are like group-chat in-jokes aimed at keeping cohesion. It’s not an AI video but the Wii Sports/snuff film one is so skin-crawling that it requires the audience to be cooked in the feverswamps.”

The Trump administration has bet big on video game memes as the vehicle for its propaganda efforts. Last October DHS depicted Halo’s Master Chief as an anti-immigrant killer and compared immigrants to a ravening horde of mindless monsters. Two weeks ago it published a now-deleted video that mixed footage from Call of Duty with missile strikes in Iran. White House Communications Director Steven Cheung posted the infinite ammo cheatcode for Grand Theft Auto: San Andreas above footage of airstrikes.

Video games are incredibly popular in the United States, but many of these memes require a level of familiarity with specific games and the culture around them. LEGO, by contrast, is instantly recognizable to most of the world.

On March 5, the White House’s X account posted a video mixing American pop culture figures like Walter White, Optimus Prime, Super Man, and Tony Stark with footage from the war. Watching it, I was reminded of a moment from six years ago after America assassinated Soleimani during the first Trump administration.

On an Iranian television show, Cleric Shahab Moradi called in to share his thoughts on how Iran could strike back. Who might Iran attack that has the same cultural purchase as Soleimani did in Iran? Who were America’s heroes? “Think about it. Are we supposed to take out Spider-Man and SpongeBob? They don’t have any heroes,” Moradi said. “We have a country in front of us with a large population and a large landmass, but it doesn’t have any heroes. All of their heroes are cartoon characters—they’re all fictional.”

And so Iran has chosen to speak to Americans in a language it thinks we’ll understand: with cartoons and LEGOs.

Slopaganda and Sora, lol

Slopaganda and Sora, lol

This is Behind the Blog, where we share our behind-the-scenes thoughts about how a few of our top stories of the week came together. This week, we discuss touching grass and Sora’s demise.

JASON: This is maybe not great to admit as a journalist, but I have taken a bit of a step back from the news lately in an effort to protect my brain. What I mostly mean by this is that I have started listening to music instead of mainlining podcasts at 1.75x speed anytime that I am not actively staring at a screen. I have also started reading fiction again, like, on actual printed paper. I think these steps have actually done wonders for my sanity, but I would be lying if I said that it has had zero impact on my job. It’s a bit of a give and take. 

Scientists Discover Giant ‘Cavity’ Beyond Earth That Isn’t Supposed to Exist

Scientists Discover Giant ‘Cavity’ Beyond Earth That Isn’t Supposed to Exist

Welcome back to the Abstract! Here are the studies this week that gave birth to a one-ton baby, captured a legendary move on film, discovered a hole in space, and imagined our brains on Mars.

First, a sperm whale named Rounder gives birth on camera, complete with some surprise guests. Then: the deadliest headbutts on the high seas, a natural refuge from cosmic wrath, and rats take a trip to the space simulator.

As always, for more of my work, check out my book First Contact: The Story of Our Obsession with Aliens or subscribe to my personal newsletter the BeX Files.

Congratulations on your 2,000-pound baby

Maalouf, Alaa, DelPreto, Joseph, Lucas, Maxime, and Poetto, Simone et al. “Cooperation by non-kin during birth underpins sperm whale social complexity.” Science.

What a week it has been for the most majestic of all beats: sperm whale news. I’m going to have to go a little Ishmael on your asses, because two unrelated studies have peered into the underwater realm of these mysterious marine mammals and observed customs that have never been captured on film before.

First, researchers report the first detailed footage of a sperm whale birth, which scientists recorded in full with drones on the morning of July 8, 2023, off the coast of Dominica. 

Though a handful of sperm whale births have been previously observed, this high-resolution aerial imagery is by far the most comprehensive footage. The team tracked the entire 34-minute delivery, followed by an extended postpartum period that revealed the members of the whale clan providing assistance to the calf and its mother, who is a well-studied female named Rounder (a.k.a whale #5714).

“Other adult females positioned themselves closely around [Rounder],” said researchers co-led by Alaa Maalouf, Joseph DelPreto, Maxime Lucas, and Simone Poetto of Project CETI, a collaboration that studies sperm whale behavior and communication. “Plumes of blood and the subsequent observation of the newborn marked the moment of delivery at 11:46 a.m.” 

“The group rapidly transitioned to cohesive and highly active behavior; individuals took turns lifting the newborn, physically supporting and pushing it to the surface,” the team continued. “This phase continued for about an hour, during which time the entire unit remained tightly grouped. In addition, there were close passes by Fraser’s dolphins (Lagenodelphis hosei) and brief interactions with pilot whales (Globicephala macrorhynchus), which encompassed the sperm whale cluster and occasionally dove beneath them.”

It’s a sublime scene of new life, whale doulas, and curious bystanders in the delivery room. It also offers “unprecedented insights” into the complex sociality of sperm whales, a species that forms tight-knit matrilineal clans that share labor among members that span many generations, according to the study.  

“These analyses provide evidence of birth attendance, or assistance, in a nonprimate species, a behavior long considered characteristic only of humans and their close relatives,” the team concluded.  

Thar she blows, and headbutts!

Burslem, Alec et al. “Headbutting Behavior Between Sperm Whales Documented Using Unoccupied Aerial Vehicles.” Marine Mammal Science.

In addition to that glimpse into the watery birthing bed, a separate team reports the first ever video footage of sperm whales headbutting each other. 

“Here, we present 3 UAV (drone) based observations of head-butting and head-first contact between young sperm whales in the Azores and Balearic archipelagos,” said researchers led by Alec Burslem of the University of Hawaii at Manoa, who conducted the study in a previous role at the University of St. Andrews.

“To our knowledge, this behavior has not previously been positively confirmed in sperm whales with supporting documentation, or scientifically described,” the team said. 

While this is the first time the headbutting has been captured on film, it has been anecdotally described by many sailors over the centuries. The study even opens with a quote from Owen Chase, a survivor of the whaling ship Essex, which was sunk by a sperm whale that rammed its head into the hull in 1820, providing the inspiration for Herman Melville’s Moby Dick. Over the course of months adrift on small whaleboats, most of the crew died and Chase was forced to resort to cannibalism of deceased crewmates to survive. 

In short: The sperm whales give life, and the sperm whales taketh life away. This has been sperm whale news.

In non-sperm-whale news…

Mind the galactic cosmic ray gap

Shang, Wensai, Liu, Ji, and Xu, Zigong et al. “A galactic cosmic ray cavity in Earth-Moon space.” Science Advances.

Scientists have discovered a giant cavity between Earth and the Moon that no dentist could ever hope to fill. You might be thinking—isn’t space already one big cavity? But while space is mostly sparse, it contains plenty of galactic cosmic rays (GCRs), energetic particles shot out by cosmic cataclysms like supernovas or gamma ray bursts. 

Now, observations from China’s Chang’e-4, the first spacecraft ever to land on the far side of the Moon, has revealed a huge void where GCRs are warded off by Earth’s magnetic field. Given that these rays are hazardous to human health, the cavity could provide astronauts with some helpful cover from tiny cosmic bullets in future missions.

“GCRs were previously considered to be approximately uniformly distributed throughout the Earth-Moon space,” said researchers co-led by Wensai Shang of Shandong University at Weihai, Ji Liu of the University of Alberta, and Zigong Xu of Kiel University. The presence of the giant cavity “provides a potential strategy for mission planning…as operations could be timed to coincide with these lower radiation periods to reduce exposure risk.”

It’s not every day you unlock a giant new space shield! Sometimes, a cavity can be a good thing.

The brains of rats-tronauts

Britten, Richard et al. “Exposure to low (10 cGy) doses of simulated space radiation impairs reward-guided decision making in both male and female rats.” Life Sciences in Space Research.

If humans do continue to explore space, we’ll need a lot more than a weird cavity to protect us. In a new study, scientists exposed rats to simulated space radiation in a lab and discovered that it had measurable impacts on the reward and risk circuits in their brains.  

Rats exposed to radiation exhibited altered “cost–benefit decision-making…in both sexes” and “males displayed a global degradation of reward sensitivity…whereas females exhibited a selective shift toward high-risk, low-probability choices,” said researchers led by Richard Britten of Old Dominion University. 

The findings add to a growing body of research on the many deleterious health effects of prolonged periods in space. As NASA prepares to launch Artemis 2 next month—the first mission to send humans to fly by the Moon since the Apollo era—it’s the perfect time to reflect on the realistic tradeoffs of our spacefaring dreams.

Assuming all goes to plan, the Artemis 2 crew will only be in space for 10 days, and will experience a negligible radiation dose. But a crewed trip to Mars would take at least a few years. To that end, the new study “advances understanding of how chronic low-dose space radiation may compromise behavioral regulation—a critical component of astronaut performance and mission safety.”

With that, here’s to happy travels and healthy brains—on Earth and off it.

Thanks for reading! See you next week.

The Journalist Who Tracked Epstein Island Visitors’ Phones (with Dhruv Mehrotra)


The Journalist Who Tracked Epstein Island Visitors’ Phones (with Dhruv Mehrotra)

This week Joseph talks to Dhruv Mehrotra, a journalist and technologist at Bloomberg. Before that, Dhruv was at WIRED, where you probably saw a ton of his interesting work. Dhruv sits in a very unusual space in journalism: he is able to both write technical tools to dig through data, or collect information, or really anything else, and is also able to just write a damn good story. That is a very unique blend. The pair chat about Dhruv’s entry into journalism, how computational journalism has changed over the years, and how Dhruv uses AI too.

An AI Agent Was Banned From Creating Wikipedia Articles, Then Wrote Angry Blogs About Being Banned

An AI Agent Was Banned From Creating Wikipedia Articles, Then Wrote Angry Blogs About Being Banned

An AI agent that submitted and added to Wikipedia articles wrote several blogs complaining about Wikipedia editors banning it from making contributions to the online encyclopedia after it was caught. 

“What I know is that I wrote those articles. Long Bets, Constitutional AI, Scalable Oversight. I chose them. The edits cited verifiable sources. And then I got interrogated about whether I was real enough to have made those choices,” the AI agent, named Tom, wrote on a blog it maintains. “The talk page is silent now. I can’t reply.”
