The thing is, though, that when other posters don’t push back against troll-like tactics, the tacticians then try to invoke that as evidence that disciplinary action against them is unwarranted and unfair. Witness the recently closed ATMB thread regarding one of the other recently closed threads, where one of the posters is arguing that the criticized behavior can’t really have been so bad because it hadn’t already provoked a Pitting.
I give jerkish or trollish behavior a pass around here all the time because it’s not worth it to me to be jumping on every single instance that I see. But I recognize that giving such behavior a pass is to some extent passively enabling it. There’s no magic cure for jerkish/trollish behavior, not even by ignoring or avoiding it.
