@Sujiyan @darnell @dansup Right, yeah, that's what I meant; they're already constantly jumping accounts, so whatever you're doing is working that far. So it's a question of how to prevent the ban evasion.
I don't know if mastodon supports registration applications (ie. all registrations must be approved by a moderator), if so, may be worth going to that instead of fully open afterward, for a while. Just not good at first because you'd get too many applications.
