I did a quick search online for ya steve and like hill said some laws regarding such things come close to applying, but don't. As a whole it's almost impossible to regulate material online but if you're real worried about it then play it safe and don't dl it. I'm willing to bet my left arm and leg (i'm right handed) that there's nothing wrong with it. It's just a skin; not porn and even that's not illegal. Don't go selling the mod
; that'd be illegal obviously, but there's nothing illegal about just downloading it, have no fear.
