Piracy and Credit Hacking
Since the release of Forza Motorsport 4, we have been closely monitoring online behavior, including the health of the Forza Motorsport 4 economy. To this end, we have flagged a number of users suspected of credit hacking. This includes both using third-party devices to hack credits as well as for receiving hacked credits (via Auction House, gifting, etc.)
We are investigating all accounts on an individual basis. After the review process, if you have been caught hacking credits, you will be console banned. If we have found that you received hacked credits, your game save will be invalidated (and you will receive an in-game message asking you to delete your save). To gain access to online features again, you will need to delete your save file and start the game over.
Regarding piracy, if you have received an in-game message indicating that your console or Gamertag has been flagged for loading a pirated disc, this is the result of your console or account having been flagged by Xbox piracy detection. If you believe that you have received this message in error, please contact Xbox LIVE Support.
We take these issues very seriously in order to provide Forza Motorsport 4 fans with the best online experience possible.
