@neil Wow, that is crazy. Is that seriously going to be an acceptable way to judge age?
I mean, the fact I have used the same email address since at least 2003 is great for proving I am over 18.
The fact I use a new unique email address for everything to which I sign up is great for proving I am not 1 day old.
If forced to use my "usual" email address to access a service, that is not "privacy respecting", is it!
