This is just about the oldest trick in the book. I know camera guys who've pulled that stunt at a casting going back 20 years. Standard line was always to say, "So you want to do b/g? Normally I'd have some male talent here, but I tell you what, you suck my dick and I'll shoot some and then send it off to see if you've got the look they want".
As old as the hills. Yes, it's wrong, yes it gives moralists exactly the right ammunition to attack porn and yes, you'll never stop it. Do you know why? Because porn attracts the lazy, the damaged and the criminal.
