The point apparently was to prevent RMT from registering, that, or protect their own asses from the so-called "fraud" they've been banning people for. Including my mule account, which is the same name as my main account, and under the same credit card. HUR DURP WE'RE SE AND WE'RE SMRT.
I think it's ridiculous. It's already prevented a few legitimate new players from starting the game (there's a thread on this very forum) and I'm sure it's going to stop more than a handful of continuing players from continuing to play. Every month I swear they just get more and more retarded.
