I do work in the adult industry, although it's on the IT end, not the performer / production end. Nice to see you here.
For those of you who don't know, 2257 regulations force any pay-site owner to have documentation for all the actors on every single scene on their site. This documentation is supposed to certify that the talent is above 18 years of age. Some of the time, it's a release form.
Other times, it's a copy of the person's drivers license! So, what often happens is that anyone who wants to use 2257 solutions that integrate with the site's CMS are actually storing drivers licenses online.
So, often enough, in order to get an actress's real information (drivers license, phone number, address), it's simply a matter of licensing content online for the purpose of selling it.
I've often wondered how many adult performers have had stalkers from other people in the adult industry with easy access to this sort of information. I'm sure quite a few.
I feel for you.
Here's hoping that the 2257 laws get struck down, or at least amended with more reasonable provisions. These kind of laws don't only benefit stalkers, but also identity thieves. What worries me with the facial recognition patterns like what's mentioned in this story is that eventually someone will be able to upload a porn picture, and get the actor/actresses private information. I imagine something like this will be made illegal, but then again, identity theft isn't exactly legal either.
