* Is reselling those digital accounts legal as per the terms of the said video game?
--Selling/buying anything related to any online video game is always against the video game's TOS, but not illegal in any country to do.It is a billion dollar industry. For example, eBay forbids it (they claim copyright issues), while PayPal welcomes it. So you could say it is a "gray area" type business that has been around without issues since the dawn of early internet games such as Diablo and WoW.
