Well not really, if the accounts that u scam are still active, then theres nothing u can really do.
If u try and merge the bnet account, then it will just get changed. If u try and transfer, they will call blizzard on monday.
If all u have is User/pass, then ur stuck with scamming gold and selling it.
As for scamming gold, try use the spectral tiger code scam (requires a 70+, well it makes it much much easier).
Just look into the scam section, and use ur imagination.
