Some people probably know them in real life. Like, you might have a friend who’s like “Yeah this [slur] wouldn’t update her mod so i posted [hateful thing] on her insta”. You could talk to them. People listen to their in-group more than randoms online.
But then again, the worst sort of people probably mostly have the worst sort of friends, and reinforce their bad behavior.
Mergers and acquisitions should be a lot harder than they are. Maybe even prohibited in nearly all cases.
