Selling the gil makes him as bad as the rmt who do it for a living. He has helped to perpetuate the rmt issue by doing it. Also because he sold gil, the poor bastard who buys the account is now flagged for rmt activities. So he has helped to fuck over not one, but two players in the game. Even though they are cheating bastards for 1. buying the gil and 2. buying the account. 3. it puts another Usless noob level 75 into YOUR endgame.
I do feel a little sorry for the idiot who bought the account. Can you imagine it, paying 300-500 for an account, then getting banned for the rmt activites of the previous owner. Not only fucked ingame, but fucked out of the RL $$$ spent on buying a now useless account. As for the friends aspect, one could be hopeful he deleted his FL prior to the sale and recommended the new owner change servers. Last player that I knew of who had bought an account was kicked out of almost every party he was in because SOMEONE always knew he was a bought account.
