As a community mod I've seen quite a few interpersonal conflicts, and one hard and uncomfortable truth I've had to learn is that often times there is virtually no way to distinguish "an abuser bullying some people out" from "victims trying to fend off an abuser" without getting intimately familiar with the situation.
Oh also good luck trying to find out how to distinguish "yet another toxic relationship between some shipwrecked souls gone wrong" and "someone got abused real bad here" from an outside perspective.
This all is not by accident, some people just know how to control the optics of a situation and how play victim really well.
