Great question, I’m also interested in the answer to this. Otherwise, what stops a malicious actor from creating and deleting a bunch so they can never be used?
Wild guess: the admin can restore the community and assign mods.
No the community can not be recreated when it is deleted. If there is demand they can pick it up with the instance administrators and the community could be purged which would make them available for recreation.
Not unless an admin purges it, I think. But you can always create it on another instance.
