That's just it... you don't. Same thing happened on Feast (I think it was a JP server), the guy had like 4 or 5 characters on the leaderboard (identical design), and named them something like Character One, Character Two, if I remember right. At this point they're just flaunting it in SE's face and nothing happens to them...so then more people do it, and don't get caught, and the cycle continues. The legitimate players there, just like the legitimate crafters on Ishgard.. they try to call out the BS but it just seems like it falls on deaf ears. Hence why I proposed a solution above that's fair to everyone. I know GMs don't have a say in what does or doesn't get implemented, but I hope they notice and take it into consideration nonetheless.
