The rules are written out so that us simple folk can understand it but it's really the same thing. If they want to get rid of you for any or no reason at all then they can.
Well my opinion of it is this, they are trying to promote a community for all of us to be able to use and enjoy safely and sanely. Sure they can get rid of you at any time for any reason, but you can also do the same. There's nothing keeping us in a "have to be here status". To me these seem like general "get a long with all" rules that some other forums could really do with having. Not too scarey imho.
