Guess some of the girls got together and are suing them; mostly for lying to them that the videos would not be distributed in the US and they were only for DVD's; and some other things. There have been some online postings from various models claiming the same thing. But, I would guess the GDP guys have a pretty good documentation process for models, so I'm guessing they are legally protected. Just sounds like their used car salesmen bits work on some of the models; anything to get them in the door. Not sure how much sympathy a jury would have for females that are paid to have sex om camera.
