Last December, we made some changes to our regional account rollback policy for players in our Asia region. We implemented this update to protect the in-game economy from the noted rise of false compromised account claims by players attempting to gain duplicate items.
This policy has proven very effective in helping reduce the number of duplicate items in the game while still allowing us to assist legitimately compromised players, and now we’re ready to roll it out for our Americas and European regions.
[What's Changing]Starting on Tuesday, April 2, all character equipment including weapons and armor restored via the Diablo III rollback service will become bound to the restored account. This means restored items cannot be traded with other players or posted on the auction house, but that they can still be shared with other characters on the account and sold to merchant NPCs.
As always we are committed to continuing to monitor the overall health and economy of the game and make additional tweaks if necessary.
[Protecting Your Account] 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.

Gold and other commodities will not be bound, only wearable items. When implementing policy changes like this that can affect the in-game economy as well as a player's experience, it's really important to us to take a measured approach.
That said, binding wearable items is a first step. We'll be monitoring how/if this policy change improves the issues we've had with false compromise reports in the Americas and Europe, and are totally open to making additional changes as needed (which may include adjusting how commodities are restored during rollbacks as well).
