RMT has been around ever since there was MMORPG. They're like the hackers. There's just no way to completely eradicate them. One way to get rid of all hackers is to destroy the earth. One way to get rid of all the RMT from ARR is to shut down the game permanently but we don't want that. SE can only slow down the RMT but can never completely get rid of them so you're gonna have to learn to live with them. An MMORPG that doesn't have RMT is a dead one.
