The Government are considering how to prevent children from accessing porn and are looking into face scanning technology.
I think this is a good idea as we already use facial recognition for verification on banks etc and if people are adults they should not feel embarassed about their choice to watch porn so no problem.
Privacy campaigners are worried about potential for blackmail though. Wish they were as worried about men illegally uploading films of their OHs having sex with them....

IABU - I think porn doesn't need age verification/existing verification is good enough
IANBU - this is a good idea
