It seems to me that you're alone in thinking that the picture linked to in this thread of comments is what you claim it is. I looked at it and I have to agree that there's absolutely no way to know whether she's "under-aged" or not.

She could easily be 18 or 19 years old. How, in your right mind, can you feel justified in vilifying a person, completely ruining his reputation, on the basis of unreasonably assuming that the girl in this photo is younger than 18?

Can you at least explain for us how you're so sure that she's under-aged? I mean, you can't even see her face.
