@JonnyT @wwahammy I share a lot of the concerns brought up. I'm just saying this does not give a potential attacker a way to be certain that anyone is underage. They can only be certain a user is an adult (if that user decided to confirm). My understanding is the system does not share the actual age, it shares a certificate confirming the user is above an age limit. An underage will simply not be able to provide such a certificate, making them appear just as those who refuse to provide one.
