Just an anecdote from Second Life, there's one person that keeps coming around despite being permanently banned and more or less not liked by most folks in one hub. He's made it his mission to dox one person who didn't actually do anything to them other than not hang with them in games like Red Dead Redemption and the like after they had one bad night. And he doesn't just do it this person but to several and all of them women. I think shadowbanning wouldn't work here but I wonder if it would mitigate the spread of such doxing if it were tried.
