This really got me laughing. It's very obvious that  the legend cherish his privacy so much, main reason no one knows him physically. 
Introducing KYC in bitcointalk is not a bad idea, but  I think its obstruction of people's privacy and many won't like this. Bitcointalk is all about bitcoin and the true concept which bitcoin is about is privacy maintenance. It would be disappointing if a forum like this is not exhibiting an example of what it's all about. Moreover,  apart from shit posting, we don't have any coin attached to the users account that needs protecting.
