That would be handled client-side, like email. You could build in a standard set of rules, and then have some kind of ML process profiles you manually mark as spam. Just have it filter profiles in API requests through the fake profile detector. > At least that was the fate of all peer to peer social networks I'm aware of. That doesn't seem true of Mastodon. The few servers I've been on were fairly tame. I think the worst I saw was someone posted a sexualized anime-style image, but there wasn't any nudity. I didn't immediately spot anything weird on Diaspora either, but I only spent like 45 minutes on there. > Also, if users are really anonymous, the system will end up turning into a cesspool of disgusting and illegal stuff. Anonymity can be okay, but only in the presence of heavy moderation. HN is basically anonymous if you want it to be, but it stays on target because of the moderation. You can see it on Reddit too. AskHistorians is a wonderful place to be; the subreddits without even basic moderation do indeed turn into cesspools. Federation has historically made this difficult because you can only moderate your own instance, which is often a minority of the content you consume. There are potential solutions for that, though. You could allow users to "flag" posts, and add those flags to the data you federate. Then, like the fake profile system, you could filter them based on user parameters. I.e. hide posts that have at least 1 "racism" flag. If necessary to prevent brigades, you could also filter the flags that you accept based on the user that flagged the post. Maybe weight them based on similarities in accounts you follow.
