Not sure of the (technical) feasibility of this, but I have some social observations.<p>It seems the motivating factor, ostensibly, is to protect children. However, the primary concern of those who don't like this seems to be with leaks and possible ensuing shaming. So, if the stigma attached to watching (non illegal) porn is done away with, the fear of leak becomes irrelevant. If protecting children is paramount then society must do away with silly witch hunts and being so anal (no pun intended).<p>While we are at it, why restrict to porn and why not extend to all things abusive to kids, including violence, racism, stupid stunts and pranks etc referenced by many other posters? Seems porn gets targeted almost always! imagine if porn were a person in the west, they would have sued the heck out of everyone.
