While I haven’t seen any of those communities on Lemmy yet, but what about communities that crosspost but for the completely different reasons. Like a post from “We love X” getting crossposted and made fun of over at “X is stupid”. Those two really shouldn’t be sharing up and down votes, and when we are at it what about downvotes? That makes bringing and bullying extremely easily and how would it be handled between places where one has down votes and the other have them turned off.
