ive not gotten ban for making too much wow gold. i still have bout 100k. mostly from AH trading.
im using tunneling service but i think coz the tunnel i use is from local ip it prob doesnt get flag.

i've also bought game time once with ingame gold and even got scammed once. both of these occur couple weeks back. i sent a ticket to blizz when i got scammed explaining i was buying game time and was kinda expecting a couple days suspension but instead i got my gold back and the scammer was ban for few days.

Sophiera, could it possibly be that the items you sell are very high above market price (500% or more) and some gold scammer drop the gold to u ? or prob something along that line where someone buy stuff from you on AH or trade with stolen gold?
