They seem redundant, selfhost seems to have a couple of rules, but they pretty much do the same thing, right?
I would prefer if they would be merged, it’s confusing and annoying to figure out which of both is bigger, since that’s all that matters. Also naming is nearly the same.
I just can’t see a difference.
I suggest simply subscribing to both and monitor which one comes on top organically. This is a direct consequence of the federated and decentralized nature of Lemmy and the other apps of the fediverse. This gives moderators freedom to enforce whatever rules are instance-specific. If one community is abused by their admins/mods, users can organically start switching to the other one and so on.
