I don't see why you would care for nudes of people that OTHER people know.
There are better girls on the internet, that are legal ;).
However if that attractiveness doesn't matter to you, and you don't know them..
That means the only reason you would want pictures is because they are child research.
well i've never taked a nude photo of myself so he better not have any! O_O
Doesn't mean he hasn't taken a picture of you ;D.
