Bungie please ban or at least temporarily ban everyone that has been abusing the code system. Just because there is a flaw in the system, it shouldn't be taken advantage of. Anyone with more than 20 codes should automatically be banned, no one spent more than 100 dollars on RedBull codes, let's be honest to ourselves. If a loyal customer purchases a RedBull and has trouble redeeming a code because the code on their can has been used (guessed) simply ask them to take a picture of the can with the code, trace the account that redeemed (guessed) the code and ban them. To those saying this isn't fair, it shouldn't be exclusive, blah blah blah... If you don't like it, then DONT PLAY!! The quest will be available to everyone for free eventually. You agreed to Bungie's terms and conditions so it's their rules.
