I would like to think there there is a solution that can be engineered, in which a service is able to verify that a user is above an appropriate age threshold, while maintaining privacy safeguards, including, where relevant, for the age-protected service not to be privy to the identity of the user, and for the age verification service to not be privy to the nature of the age-protected service being accessed.
In this day and age, of crypto, and certificates, and sso, and all that gubbins, it's surely only a matter of deciding that this is a problem that needs solving.
(Unless the problem really isn't the age of the user at all, but harvesting information...)
