Fediverse-based platforms usually just don't do any proactive moderation. They rely on users spotting violations and reporting them. The reports are federated though. If admins of two servers disagree on what should be allowed, that usually leads to a federation block between them.

There is some proactive moderation on new servers in my experience. Servers belonging to certain controversial/unpleasant content groups are often blocked beforehand, for instance. Certain porn-oriented parts of the Fediverse basically exist as their own islands because nobody wants the moderation burden.

I think these federated platforms can use some kind of spam detection, though. A bunch of Japanese teenagers completely swamped most of the Fediverse with a shitty prank on another Discord server for instance, and there was that time someone automated posting CSAM across a few servers. It all kind of feels rather 1980s internet in a way, clearly not set up to deal with intentionally malicious people.

I plan to explore this in Smithereen (my fediverse server project) at some point in the future. Ideally, I want something similar to VKontakte's "nospam", where moderators would create some sort of templates that all content goes through, and if there's a match, a violating post would get deleted, or its author's account suspended, or just a report created for further manual review, or whatever else the moderators deem necessary.

Yeah, I remember that. That was what got me thinking about spam filters. The posts were all the same, a simple substring match would do.
