My understanding is currently they do not vet user age. How could they? There are a few billion users. Even among different ethnicities people look younger or older depending on the society they group in. However, I was looking at this from a "confidence score" perspective. If it's an open secret that employees do nothing, throw AI at it to flat likely-to-be-underage users. Then throw what portion of employees you can at that effort, rather than vetting ~2 billion users.
