Hexbear has one. It’s not federated now, but plans to be by next week. Might be one elsewhere too, just the one I know of

I don't think they federate, but hexbear.net is what chapo's corpse became.

Kind of? I think a lot of the people who used to hang out there are off in their own fork from Lemmy called Hexbear.

There's Hexbear. But they're not federated.
