@Sheril At least here is an infrastructure and admins willing to help. It is possible to either have harassers blocked by their host, or their unwilling host being blocked by other instances. I don't know if good will is enough to solve the problem, but exactly that was lacking on Twitter (in summer my account was disabled because somebody has flagged a tweet by me from *2017* about having my teeth fluoridated; I had to delete that tweet, but racist etc. stuff is a permanent menace).
