It’s not, it’s a 3-year-old instance that is a leftist umbrella community that aligns closely with left unity, socialism, and communism. They are very anti-capitalist, pro-lgbtq (why they have pronouns with their names), and they don’t have a downvote button.

They say “shitposting is a culture here”, but they mostly leave it to their own communities. They have been defederated until recently, so it’s just recently become a hot-button issue. .world defederated, my instance (Midwest.social) did not. I don’t mind them. And, like .ml or lemmynsfw, if I did I would block them myself.
