It is perfectly possible for an operator to independently get your approval, or apply a rate-limit, a time limit, a kind check, anything it wants. There are currently two implementations of operator servers out there, but there could be many other variations and people could pick the ones they prefer. If Nostr and Pomegranate get more popular I expect to see lots of these servers out there with different policies so everybody can be happy.
