I think we should start a list of boosters and cheaters we run into online and post it to the website. It would let us know who to avoid, report, and recruit. I think it would be a good edition to this website. Well thanks.
The problem is people always change their gamertags every 6 months usually so there is no real way to prevent them from entering the community if they change their name. The closest we have to what you suggest already exist and is known as the DNR (Do Not Recruit) List.
