quakers.social shows up on our list of blocked instances, but looking at the most recent posts at https://quakers.social/public/local I can't see why. They seem like a harmless group with a lot of religious reposts. Does sh.itjust.works have a policy of reciprocal blocking or something like that?
We asked them if they wanted to stay federated and no one spoke up. (Quaker joke I don't actually know the answer.)
