Not really, but there are some communities I refuse to post in, and certain kinds of posts that I always disable notifications for, because I know I am going to get the nastiest, ugliest notifications because lemmings refuse to acknowledge that I get the notifications and not Trump or Hegsheth or whomever. If I misjudge something and it starts to draw awful responses, I just delete it -- there's nothing to be done to stem the tide otherwise and deletion fixes the problem pretty immediately without any downside to me.
