Do not attempt to sell items, zeny, or accounts for out of game items or currency. This includes all types of items, both electronic and physical. If you buy items, zeny, or accounts with out of game items or currency, we reserve the right to confiscate the purchased items without compensation or warning.
According to the rules, the seller gets to feel the wrath of the ban hammer, and the buyer gets his stuff confiscated. Maybe he's just temp banned since the case is being investigated?
Or maybe he's hiding stuff that he should tell, like, who his "friend" really is, and so on. As we all know, RO players don't like to betray their RO friends, and since it's a case of RMT, it's most likely a RL friend, and maybe both of them were playing from an internet cafe, and as a result due to the same IP, both of them are banned. Ahhh, how I hated those internet cafe cases.
Anyway, who wouldn't think that buying stuff with REAL MONEY from other persons except the GMs/donations/ad credit shop would be legal? This is not allowed in ANY MMORPG.
Did that Kane guy say that you could recover your banned account for buying something with 50 ads? Hahaha.
