What do you mean "finally"? What exactly is actually wrong with selling NX for in game currency? As long as both sides are sincere about it and there's no scamming involved I find the notion of it being a bannable offense to be outright retarded. Maybe Nexon should make their game actually feasible to play without the need for it.

aside from the fact that it's explicitly against the ToS and even warns you via mapletips that pop up in the chat saying that cash trading is forbidden?

I mean when there's that many things telling you not to do something, shouldn't that be taken as a sign not to do it?
