Which then wouldn't be a legally full verification of your age, thus the legislation would probably require some other means. We currently have a similar discussion in the EU regarding porn sites. Verification methods could be showing your id card and your face to a webcam, or showing up at a verification office in person (at least in germany we have this with our national postal service). Of course the porn sites don't want to implement this. And I cannot really blame them. Nobody would give a random porn site their real identity and it would still be very easy to get porn without verification.
Age verification on social media is very similar.
I really love the continent Zammonien from the books by Walter Moers, like "The 13½ Lives of Captain Bluebear". Just to give you an idea: In one life bluebear goes to nightschool - a school in a mountain lead and taught by an Professor Dr Nachtigaller, who has 7 brains - together with a moutain demon (kind of) and a prince from the 2364. dimension (where everything is made of carpet and people make music on instruments made out of milk) named Qwert Yuiop. Later bluebear gets to the sweet desert, which isn't filled with sand but with sugar. For the nomadic people of the sweet desert he catches the half-stable fatamorgana City "Anagrom Ataf" in a big pool of molten sugar. You get it. Bluebear being the kings of lairs at one point in the book really fits.
Moers wrote multiple books about that continent. I really love them. I just organized a big station based game about that for my local scouts troop. About 60 kids from 7 to 16 years following my story to rescue Zammonien. Easily dumped 150h of work in that game, but it was really great
