There are a lot of tanky posts coming from lemmy.ml. Their whole purpose seems to be to troll and spread their bullshit far and wide. They are nearly as bad as the alt-right. They argue in bad faith and celebrate authoritarian oppression. The beehaw mods might want to consider defederating.
My understanding is that a lot of the reasons for defederation stemmed from a fundamental lack of sufficient moderator tools. Tools that have not appeared and the lack of which has prompted Beehaw to consider moving to a different ActivityPub supporting platform in the fediverse.
