@Avner As in offline society, vulnerable or underrepresented groups have leaders (usually bigger accounts) that keep the peace within their communities and defend them against outsiders.
There was a group (it's still around, but much less active) of women who took on issues of creepy guys. They'd lead a pack into the guy's mentions and expose the rotten behaviour.
But this kind of community moderation takes time and effort, and so there were some "buy me a coffee" type of set-ups started. Unfortunately, those mods get to rely on such income or love the sense of power, and there's a tendency to start faking trouble to keep the cash/drama flowing if there are no outside issues.
This is the origins of real mafias - communities paying their own for protection, then it getting out of hand. It's been an online issue for a long time, and Bluesky's weak central moderation system and "competitive" environment encourage it.
