yeah, its rather ...not good to sell an account, I know Blizzard will ban/black list any player that tries to sell their WoW account from any and all future games.
Sold your wow account and still wanted to play starcraft? sorry banned, Wanted to play Diablo? banned. wanted to play hearthstone, banned, overwatch,banned, HoTS? banned.
had a friend who did that and got caught and even trying to do a new email and everything and still wouldn't let him so I inherited his Legacy of the Void.....which I don't know what to do cause I don't play StarCraft
