So this happened a while ago, My account had been hacked a while back, All my blue gear was gone, (Barely worth anything). Sooo... once I logged in one day and found that I was missing my gear I logged off, and like 2-3 months later I started playing WoW again, submitted a ticket. They told me it would be hard to retrieve my items again.. I sent in a note with the Items I thought I had lost, some of them I was sure about.. They still didnt restore any.. but they gave me 350g //They actually gave me 350g before I sent in my list of lost items... .. .. Yup..).. (I know crappy amount but still.. Its gold given by gms That I didnt have before.) Okay so now on to the possible exploit.
So, Let's say you logged onto a computer in .. maybe the library, sell/ disenchant (Probably the best idea) all your blue/green gear? Then went back home, logged into that account 2 months later. (I never said it was going to be speedy..)? make a ticket. Say you dont remember any gear that was lost. Then they SHOULD send you an amount of gold to possibly make up for the gear you "lost" before.
Again, This is not a way to get QUICK gold. But for you bright people out there. Use it to your advantage O.^
