I get you are mad, but why would they buy you a new disk. You weren't even banned one week. They didn't make you get rid of your disk. Did you sell it or throw it away?
Even if you were banned you could have played offline which is what a large group does anyways.
Someone accused of a crime spends nights in jail during their trial. If they are not guilty they aren't compensated for that week or few days. The Show isn't going to compensate people who are mad they were banned for like 5 days
