IMC, you do realize that even if you 100% banned all forms of trade; no money, no items, nothing, that RMT will still exist for the game?
They will just sell individual accounts that they bot up and level and amass gold. Making an account is free, so if they get caught in the process they’ll just make another.
Point being, you’re blowin’ it on the subject of anti-rmt measures, blowin’ it real badly, and at a huge cost. The truth is there isn’t anything you can do, you have to learn to co-exist with the RMT business in a way that best suits you, you cannot, and never will block it out. Every successful MMO has RMT and deals with it in a reactive form. You’re doing it in a preventative form that only hurts you, while displaying a very sheer lack of understanding of how RMTers even work, and a seeming ignorance of how it’s affecting your players.
That’s really all I have to say. Stop trying so hard to kill the RMTers. It won’t happen. Learn to live with them. Find a middle ground.
