I don’t know, don’t have an instance. If it’s not just an option to still be federated but to opt out of having community posts being featured in all then maybe they should defederate with all of the other ones so they can post terrible things about the people they hate behind everyone else’s backs. Or they can just accept that when someone (even a mod) posts something antagonistic, it’s going to get down votes.
I seriously doubt that vegan posts showing off durian jerky, or even posts about how long cows could live if the meat industry didn’t slaughter them at peak profit efficiency, would be downvoted that much.
Lord forbid they get the password used to protect the data that they stole!
