say there are three instances, A, B and C. if A is not federated with B, users from those two instances can’t interact (right ?) but what if both are federated with C ? would both indirectly be able to interact ? if there is a post on instance C and a user from B comments on it, would that comment be visible on all three instances ?
Basically, every major instance that isn’t sh.itjust.works, lemmy.world, lemmygrad.ml, or exploding-heads. They moderate in favor of “federate by default, defederate if it becomes a problem, refederate if the problem is addressed”
