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.

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

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

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.

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?...

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.

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
