Had this idea a few time ago:
Using a $5 battle.net new account, I buy transmog items at the auction house, at high prices. Obviously, the seller of the item was the wow gold buyer.
For example, I want to sell 20k gold at $25 to my customer. I'm chatting with him on skype. Running my TSM app, I can find great deals in the ah transmog market. While my costumer is charging my PayPal account, I run TSM app and, after a quick scan, it advertises that [Hellslayer Battle Axe] is selling at 200g, (market value=4k gold) and [War Pain Chestpiece] is selling at 150g (market value=2k gold). I can tell my costumer to buy those two items and flip them in the ah again, respectively at 12.800g and 7550g. I will obviously buy them.
So, my costumer receives 20.350g (20k, considering that he spent 350g before), and I think that there isn't any suspect transaction here. Of course, a character constantly buying transmog items at ridiculously high prices can seem to be too retarded to be able to play wow, so the situation can be suspect, but blizz just doesn't have any proof of gold selling.
The only problem is how to transfer gold between my own accounts: if i'm the owner of both accounts, the transfer is safe but my main account is linked to the one I use for gold selling, so I can get both account banned; if I create my gold selling account using a different name, the two accounts are not linked, but the gold transfer itself can be flagged as gold selling, both using f2f or gbank withdrawal methods.
What do you think about my idea? Do you think gbank withdrawal is already a safe enough gold selling method? I don't care about my $5 battle.net account, as I plan to buy one every month, but I'm afraid I will get my main account banned.
