The Banhammer Strikes

Bungie has started to make true it's claims of not letting players cheat on Halo: Reach. Just days ago, Bungie performed a credit reset to 15,000 players, who were apparently using an exploit that allowed them to complete a challenge more than 20 times in one day via network manipulation. The affected players will lose all credits and progress, however will still hold their commendations and will need to redownload any extra DLC armour they had. Reach players be warned, Bungie is shining up its banhammer, and they WILL use it.
