giving models info to a affiliate or to someone who buys content ,has nothing to do with any privacy law.I dont know who came up with this? Adult mag publishers have been doing this for years. My wife shot for a adult mag(got the cover

,the photog who shot her was a freelancer he sold the pics to the mag and that included all her info. Its done all the time in the real world. As for lens if your going to give them the info what are u waiting for the time is ticking? I would assume the 80/20 rule applys here. Meaning 80% of the sales are made by 20% I would take care of the 20. Also I would think about no one becomes a affiliate who incorporated with a tax id number. It saves you money no more 1099's and the person has put some skin in the game.
