As in, if I upload my own artwork to the game, I don't want it to be sold in the Market. I don't want people to buy and use it as their character's "appearance".
Each alter ego is supposed to be different in appearance from one another. Take mine, for example... no one wear the exact same equipment as she does. I'm not too fond with the thought that my elf have the same face as, say, an elf that just joined to Tweeria. I want to be allowed to upload my own artwork freely, for my own use, so that I can update the artwork each time my alter ego wears different armors.
