This is what i've heard regarding this. I'll say right now, i'm definetley no expect on this matter.
I was under the impression that displaying underage girls in suggestive poses (girls bearing their asses covered wearing nothing but a g-string is suggestive in my opinion) is illegal. Whether they be nude, or even wearing something like a bikini.
If you're going to do non-nude, there are plenty of 18 + year old girls willing to slap a pic up on these things. A prime example of sites with chicks like this... ratemypicture.com, ratemyprofile.com, facethejury.com
They have underage people on them, but nothing that is anywhere near as suggestive as a 13 year old girl brandishing her ass for everyone to see.
