Good work, Shep.
Selling (or buying) account information is perfectly legal and moral. It's the hacking that's the problem, and I don't know if we've proven torac a hacker, but he's certainly selling 'hot' info, and seems to know it. Time for a scammer tag, at minimum, I think.
buying/selling account information is only legal if ToS or Admin of the respective websites permit it. There is precedent though in certain areas for the transfer of property contained within an account (first-sale doctrine should apply to transfer games from one account holder to another account holder), but the account itself is usually owned by the business, website owner, or individual that administers the userdb.
