Am I missing something? The community you linked only has one post.
I’ve noticed the user you’ve mentioned reposting some of my greentext posts to similar communities on different instances (and vis versa), but that seems harmless. Maybe even a needed service.
Thank god. I’ve been annoyed by their toxic nonsense.
This is like when the one insufferable dude at a party leaves on his own, and now the host doesn’t have to say something.
Congrats!
