Actually, I think the moderator admin is somewhat useful. The game by default has a very narrow difference between super admin and admin -- super admins just can't be banned. It doesn't make sense that the lowest level of enhanced power can do everything the highest level of enhanced power can do. The game by default should prevent admins from doing things like clearing/loading bricks, changing environment, permabanning, etc. The moderator position is useful for allowing players to moderate the players on the server without having the power to completely forget up your server in your absence. Sure, you can say "don't make people you don't trust admin then," but at the end of the day there's no reason you should have to trust those people with your entire server when all they need to be able to do is kick/temp ban.
