I guess the scam probably works because so many people watch porn and such a significant percentage of them are ashamed of it, that it’s just a numbers game.
I can’t imagine too many men being vulnerable it, because when men are among themselves with no women around, they tend to be pretty frank about the subject.
Interestingly, my scammer seems to have found me through Facebook, given some of the assumptions he made about me. He was targeting me because I was a gay, perhaps thinking I would be ashamed of that.
He picked the wrong guy. ;-)
