Hello, a while ago my WoW account got hacked. After I got the account back my chars were nacked and much items stolen. So I wrote a ticket to a gm and told him the story. He said that they will check it and give me my items back. One day later I got all my items in my mailbox. But I also got other epics that i sold a while ago (like Nethervortex) to other people back. So I had double profit from them.
A few days ago my account got hacked the second time. I wrote again a ticket to a gm and the same thing happened. I got random epics (like Staff of Natural Fury) back that I sold in the auction house a time ago.
So I thought that you maybe can dupe items through this if you talk to a very good friend and tell him that he should change your password and "steal" a few items. Or you can let him sell a few random epics and let restore them so he got the money and you still have the epic.
Sorry for bad English.
