I've been looking forward to this panel on AI companions with @meetalijain.bsky.social all day. This one is going to be spicy 🔥 #TSRConf

Lunch over! Now I'm attending a set of lightning talks on "AI and Algorithm Auditing" - starting with Rafal Kocielnik's talk on democratizing AI auditing #TSRConf

Complicated live skeeting logistics! I'm in the "Understanding Online Environments" lightning talks, where KGI's @alissacooper.bsky.social will be presenting, and then I'm scurrying over to the workshop a workshop led by my colleague @leticiabode.bsky.social on publicly available data #TSRConf

Next up at #TSRConf! Research presentations on online harms. Missed the first couple of presentations (lost track of time having great conversations!) But now we're back in action

Day 2 at #TSRConf! @stanfordcyber.bsky.social's Jeffrey Hancock is interviewing Australia eSafety Commissioner Julie Inman Grant, a true rock star of online safety ⭐ I'll try to cover this conversation as I eat breakfast

Wonderful day 1 at #TSRConf. Fascinating and needed discussions of AI and content moderation, risks to youth, and new tools for trust and safety. Always really nice running into familiar faces as well.

Next up Youth Risks 2! (Turns out it's not tomorrow as I previously reported.) #TSRConf

Next research talk at #TSRConf - Youth Risks I! (There’s a studio-mandated sequel tomorrow) I’ll be skeeting the highlights

Awesome research talk by ROOST about Discord open-sourcing a trust and safety tool called Osprey. It can be used by any platform on a permissive license. Love the spirit of sharing 🎄 #TSRConf

I think the TLDR is you can tell a chatbot that a prohibited request is for a benign purpose (eg writing a story about building a bomb for English class) to short circuit the model’s safeguards

Next up! Live skeeting “Content Moderation and AI Alignment” with the brilliant @whiskeyocelot.bsky.social. Great line up so far @stanfordcyber.bsky.social 💡 #TSRConf

KGI's @zanderarnao.bsky.social will be live posting from #TSRConf - be sure to tune into his account to follow along!

Tune in as I live tweet @stanfordcyber.bsky.social’s Trust and Safety Research Conference!! #TSRConf

The just-announced $2.5 BILLION settlement between FTC Consumer Pretection Bureau and Amazon should rattle Live Nation pretty hard.

🚨Antitrust & digital competition are in the news almost daily – from decisions issued in cases against Google search and ad tech to DMA enforcement actions involving Apple and Meta and new private litigation in multiple jurisdictions. 👇

We built the simplest possible social media platform. No algorithms. No ads. Just LLM agents posting and following. It still became a polarization machine. Then we tried six interventions to fix social media. The results were… not what we expected. arxiv.org/abs/2508.03385

Can We Fix Social Media? Testing Prosocial Interventions using Generative Social Simulation

Social media platforms have been widely linked to societal harms, including rising polarization and the erosion of constructive debate. Can these problems be mitigated through prosocial interventions?...

🚨New op-ed in @newsweek.com by KGI’s @alissacooper.bsky.social and Eric Rescorla: Yes, Chrome really *can* survive without Google. This article breaks down how the proposed Chrome divestiture as part of the US v. Google search antitrust case is technically feasible www.newsweek.com/yes-chrome-r...

🚨NEW Report: The Technical Feasibility of Divesting Google Chrome 🚨 Our report shows a Google Chrome divestiture is technically feasible and offers an engineering assessment of what it would take to separate Chrome from Google – and succeed: kgi.georgetown.edu/research-and... #USvGoogle

Former AG Barr: "This isn’t a case in which a company has gotten power over the production of vacuum cleaners. Google’s dominance allows it to operate as a gateway to the internet, the digital world through which Americans engage in almost all interactions."

Opinion | Google Faces Its Monopoly Reckoning

The Justice Department’s proposal that the company share data, shed its Chrome browser, and cease exclusionary contracts deserves broad support.

The #USvGoogle remedies trial is about to start! Anyone can dial in to Judge Mehta's courtroom to listen the opening statements 👀 www.dcd.uscourts.gov/public-acces...

what privacy? how would it degrade quality? and what about the fact that Google is already rife with ad fraud?

Very bad that mainstream media keeps accepting the premise the Trump admin is “cracking down on antisemitism”. Everyone knows none of this has anything to do with “antisemitism” it has to do with snuffing out any dissent over Israel’s genocide in Gaza and purging brown people from society

On campuses nationwide, many students are saying that the Trump administration's efforts to crack down on antisemitism have caused a chilling effect on speech and political activity. By @elenamoore.bsky.social

UChicago's Randy Picker calls @matthewstoller.bsky.social a "smart entrant" into the news media market. Anti-monopoly is good attentional business strategy 💵 #StiglerAntitrust25

@competitionprof.bsky.social asks - would George Stigler approve of regulating big tech? See Stigler's foundational paper 👇 www.jstor.org/stable/3003160 #StiglerAntitrust25

These disclosures are indeed an opportunity for a humble brag @matthewstoller.bsky.social #StiglerAntitrust25
