Zurich University AI Researchers Ran Secret Test On Reddit Users
The undisclosed experiment prompted backlash from moderators and a firm response from Reddit’s legal team.
Researchers from the University of Zurich quietly ran a months-long experiment on Reddit’s r/changemyview (CMV), using AI-generated comments to test how persuasive large language models (LLMs) could be. The subreddit, home to 3.8 million users, invites debate on controversial opinions — but moderators say the AI replies crossed ethical lines.
“The CMV Mod Team needs to inform the CMV community about an unauthorized experiment conducted by researchers from the University of Zurich on CMV users,” moderators wrote, calling the study “psychological manipulation”.
The experiment involved AI-generated responses written under fake identities — including a trauma counselor, a sexual assault survivor, and a “Black man opposed to Black Lives Matter”. These posts were crafted to sound human and emotionally resonant. Some remain accessible via an archive maintained by 404 Media.
The researchers went further by tailoring AI replies using personal information inferred from users’ Reddit history — details like age, gender, and political leaning, all generated using another AI model.
Moderators say this violated subreddit rules, including bans on undisclosed AI use and bots. They’ve filed a formal complaint and asked the university to halt publication of the research.
Reddit responded strongly. Chief Legal Officer Ben Lee called the study “deeply wrong on both a moral and legal level”. Reddit has since banned the accounts involved and is improving its ability to detect fake or AI-generated content.

“We have banned all accounts associated with the University of Zurich research effort,” Lee said. “We’re also working with the moderation team to ensure all related content has been removed”.
The researchers maintain the study was approved by their university’s ethics board and claim it offers valuable insight into how AI could be misused at scale. “We believe the potential benefits of this research substantially outweigh its risks,” they wrote in a Reddit comment.
But CMV moderators pushed back. “People do not come here to discuss their views with AI or to be experimented upon,” they wrote. “People who visit our sub deserve a space free from this type of intrusion”.

Instagram Redraws Its Wordmark And The Internet Reads “Instagzam”
Instagram’s first wordmark refresh in a decade arrives with new fonts, a restrained gradient — and a Reddit verdict of sidegrade.
Although Instagram’s famous camera icon hasn’t changed, the company has refreshed the handwritten wordmark at the top of its app. This is the first redesign we’ve seen in ten years, and one the internet promptly set about renaming.
“The wordmark at the top of the app hasn’t changed in 10 years, so it was time for a refresh,” Instagram head Adam Mosseri wrote in a post on August 13, describing the new version as “cleaner and more modern” while keeping references to the original design.
Instagram says its team explored hundreds of options — all-caps lettering, camera-inspired concepts, even literal handwriting — before returning to script. “Script reflects individuality, so referencing that felt right,” Instagram director of product design Jasmine Probst said in Meta’s announcement. “The new wordmark is bolder and simpler, with touches of unexpectedness. It cues individual expression, a personal voice, both of which have always been core to Instagram”.
The wordmark is part of a broader brand overhaul: an updated Instagram Sans typeface, two new fonts — the hand-drawn Instagram Pen and Instagram Mono — plus refreshed motion and layouts, and more restrained use of the signature gradient. The wordmark is rolling out globally now, with the rest arriving throughout 2026 and beyond.

The design mixes cursive and print lettering, some characters connected and others floating free. That hybrid approach, combined with unusually shaped “s” and “r” characters, led some users to conclude the logo actually reads “Instagzam”. On the r/logodesign subreddit, one user said the wordmark looked “fan-made,” like something built in Canva; another called it “an unsettling mix of manuscript and cursive”; a third summarized it as a “sidegrade” — or, inevitably, a “zidegrade”.
Not everyone was hostile to the new look. Some found the half-cursive design stylish and surprisingly readable, while others called it an improvement on its predecessor, and one commenter argued Instagram was simply adopting minimalist branding later than everyone else. Either way, the platform now has a refreshed identity, three updated fonts, and an unofficial new pronunciation.
