Having just done a little of my own detective work and found out who Kahn and his brother are, I would like to retract my previous comments about him, or at the very least qualify them somewhat.
I don't believe Kahn hides his identity to protect himself and his interests outside of porn (although I can see that he also has his reasons for doing so) as much as he does so to protect the identity of his brother and his career, which is extremely understandable and indeed somewhat commendable too. If a mainstream media source were to join the dots between the two of them, I believe it would be potentially disastrous to the career of Kahn's brother.
Anyways, that's me tapped out on the subject....
