POV porn exists, you could just actually work out an agreement with a strip club to basically rent it out to do a shoot one day, if you wanted to end up with pretty much the same kind of video, except everyone involved actually signed up for it.

But that's kind of the point. They want people who didn't "sign up for it". That's part of the allure for these people. And for the viewer side as well. I have literally watched people angrily debate that a video depicting such things was "faked" and that counted as a negative for the people who watch those. I honestly don't get what the difference is between a person who's getting a paycheck and somebody who's being stalked and fucked with for somebody who's watching that sort of content. But sadly they exist in far too large numbers.
