I'm betting that even if you DO have a stipulation in the model release stating that private information may be given out to other businesses, the models will still have a strong argument when it comes to mass publishing their private information.
Especially when it comes to passing it out to every little affiliate
With the US Privacy laws being what they are, it's going to be tricky..
Additionally, some contracts signed in 'good faith' are easily overturned..
In otherwords, if the model doesn't understand what she read, yet signed it anyways, or didn't read the contract fully, then the contract can be rendered not legally binding...
At least, that's how I understand it....
Short of having her on video, with you stating "I'm going to give your ID to anyone who requires it, which may number in the hundreds, do you agree?" and her agreeing to it, you may have to remove the content if she sues you..
