Personally, I report them as soon as I get the chance and target them in multiplayer games, even if that means throwing.
I know mods won't do much in games where the issue is a coded thing like 1488 or HH, but I can sometimes derive pleasure for calling them a piece of shit and making a good time out of giving them a bad time.
Is there anything better/more to do?
target, taunt with barbara pit memes, get really sweaty cuz clowning on them matters a little more than most matches
