That's quite concerning indeed. Especially that he told that he didn't have the skins expansion. At least he didn't claim to be the author, but still, credits should be given for such work.
Please
Roro35 , always make it clear when a build is not your work, especially when you propose it for download you should credit the author.
We clarified this very recently, so you could legitimately ignore it when posting, but we have set some rules about that kind of situations:
Regarding the Intellectual Property on the Forums
Please make sure to read them, and to be careful about this in the future. Exceptionally we'll be nice because the rule is new and because you're a newcomer, but we might take this in serious from now on.
