Fediverse

Not necessarily puppet accounts, just brigading in general.

It's the rationale many instances used to defederate hexbear. (Even though iirc hexbear disables downvotes, so they're defederated for users mass posting, usually that hogshit image, instead of mass voting.) It wasn't puppets or bot accounts at any rate.

But then there's repost communities where users share comments (especially in places they or their audience is banned from) or DMs for a group response.

Not to mention the whole 'block and downvote all .ml on sight' mentality. But hopefully that might be something this tool could catch.
