These are arguments that I stay out of. First, I don't disclose any information about people I know unless I've cleared it with them first. Second, I don't know nearly as much as I wish I knew, and as I have gotten older, I have come to doubt much of what I once knew to be true.
About 20 years ago an agent named Jim South was indicted for using an und3raged model in a porn flick. He had a copy of her birth certificate and a copy of her passport, both of which showed her to be of age. He was eventually cleared, but it was a fight.
So, guys, if he was "wrong" when he had a copy of those documents, how certain are you of Yulia's birth date?
