Does it have to be calckey specifically? If not, ubiqueros is misskey and rage.love is hometown. Blacktwitter.io is running normal Mastodon I think. Fediverse party lists neovibe.app (Mastodon) as Black-run. Weirder.earth (Hometown) has strong antiracist moderation but I don’t know the composition of the mod team offhand
I remember seeing a recently formed Black queer instance being posted about but I don’t remember the name, and of course because it’s Mastodon there’s not really a way to search for it 🙄 but I’ll see if I can find it edit got it: blackqueer.life, running Mastodon.
