Ever since hats became available in the Spy and Sniper update, TF2 players have coveted them above all other items. The hats were extremely rare, and users who racked up the hours were left hatless. Someone got a little tired of not having a hat and created an idling program which would allow users to appear to be playing the game when they actually weren't. Valve officially announced that it was taking a stand against these idlers. Any items accrued through the use of the idler will be deleted from the players inventory. Future offenses will result in all items being removed, even if they weren't obtained through idling. Players who didn't use the idler will be receiving a free hat in their inventories soon. I opened TF2 to find an Engineer's Cap, but most users reported receiving a halo.
