Why does my character skin keep reverting to a naked girl?

Well, if you're a premium user I wouldn't know why, but the Anjo Caido (pirate'd) Launcher (the force update one) gives you a naked girl skin for fun. Also some hacked/cheat clients do it too.

It seems by disabling all mods and removing the painterly texture pack fixed my character's skin from being reset to a naked female.
