I don't want to come across in a bad way here but to answer your question... What gives you the right.

It is their game they can do what they want with it. If they so wished they could ban you for no reason, take you character naked into any town they liked and make all the mobs in the game do a merry dance round you.

Hope this helps in some small way.

People need to understand that you are basically renting the game. Getting a copy of the game doesn't now make you the new owner who can throw up their hands in rage at anything you don't like.
