We deactivated these keys because they keys were purchased with credit cards where the card-holder initiated a charge-back. A charge-back is a consumer protection mechanism offered by payment companies such as Visa, allowing a card-holder to dispute a charge on their credit card statement. This means we never received payment for the game. In fact, we were charged a fee by the card issuer for the charge-back. For these 1,341 keys, these fees totalled around $30,000.

We dont know how exactly these sites obtain their Steam keys. It seems likely that they were originally obtained from our store using stolen credit card information. Keys were then sold through a handful of questionable sites to people using legitimate credit cards. The owner of the stolen credit card ultimately disputed the charge and we lost the sale. In total, we lose ~$45 per transaction of this kind, due to the charge-back fee (~$22 fee + $25 game price). Meanwhile, the unauthorized key reseller kept the money from the player who ultimately received the bad key.
