Facebook already requires users to tell them their age, and already mandates minimum ages for users in their T&Cs. Recent and current lawsuits establish that /this is not enough/. Hence, mandatory age checks involving some combination of government ID and face recording, and a big database proving you've done that so you don't get fined when kids get on your platform.

We're literally about to require Meta to prohibit the creation of multiple accounts. Their T&Cs already prohibit that, so what we're saying is that just asking is not enough - we are demanding it is enforced. What we ask for, we get.
