I am on the board of ROOST, the Robust Open Online Safety Tools effort. The idea is to counter harms such as child sexual abuse material not by sending every private chat to some central service, but by training local models that run on laptops, under a community code of conduct. For each incoming piece of content, the system can produce citations in a way that people can contest, with a reasoned audit trail. This is already in production through communities and platforms including Discord, Bluesky, Roblox and Notion.
