I think what they really need is an autosubscribe, so you can autosubscribe to /c/Piracy on all federated servers. (Then of course be able to block certain instances if they're horrible)

I posted another way to (potentially) fight back here as well (something to make for users, not just mods to use to fight back): https://lemmy.world/post/212583 Looking for thoughts on if it would be effective.

Ability to block instances at the user level should be coming in one of the next updates
