While you can argue mothy's statement was a suggestion rather than a cold hard "It is Karchess," it is a suggestion that he followed up with a reasoning by which we ourselves try to determine names in this series-- "Karchess since it's supposed to be based on KAITO's name."

We're purely arguing by aesthetic in cases like these, when the Japanese spelling does not perfectly match any pre-existing names.

Mothy's statement is a suggestion, but it is a tie-breaking suggestion, in my opinion, which trumps "Curtess looks more like a real name" which falls apart as an argument for accuracy when you have all these other not-real-name characters.

And as you pointed out, he did tell us this to help solve the dispute.
