We know that having your account compromised = zero fun. That's why we provide an account-rollback service that helps get players back into the game as quickly as possible. However, we’ve found that a number of compromised account claims are actually fraudulent attempts to get extra items and based on this, we've decided to tweak our rollback policy in the Asia region to allow us to continue assisting players while also protecting the game economy. This change is in addition to our zero-tolerance policy against filing fraudulent claims.
As of 12/18/2012 at 11:00 am (local time), all character equipment, such as weapons and armor, restored via the Diablo III rollback service will be bound to the restored account. While this means that these items cannot be traded with other players or posted on the auction house, they can still be shared with other characters on the account and sold to merchant NPCs. Note that gold and commodities restored via the rollback service won’t be bound to the player’s account. As always we are committed to continuing to monitor the health and economy of the game and may make additional tweaks if necessary.
Considering that the rollback service is intended to help players whose accounts have been compromised, we obviously wish that no one ever needed to use it. The best way to help protect yourself from account compromise is to secure your PC and Battle.net account, for example by adding a Battle.net Authenticator. While no security measure is completely foolproof, we've often found that many accounts are compromised a second time simply because players do not take any action to protect themselves after being compromised the first time.
The game economy is important to the quality of the player experience. Anyone who attempts to gain extra items through false claims is potentially causing harm to the game, the economy, and the experience of other players. By strengthening our policies against dishonest claims, we hope to provide further stability to the economy and an even better gaming experience for all players.
