But he's not really 'exposed' online, as his face is obscured. Better question is how you found the video. Did he show you it? Did you find it? How easily can you find the video? Is it circulating on many online porn sites? And what are the chances of others finding out it's him?
Another good question is if he wants to make any more. It might just have been an experiment. One of those 'naughty' things, that you do once, and never again.
Was looking for amateur porn in my country. And recognized him on xvideos.
