...and you think 14-17 year olds won't circumvent this in mere seconds? Like, they'd just sign up at an instance that doesn't implement these labels, or doesn't care about them, or use their parents accounts, or ask them, or an older friend to sign them up, and so on. Even if age verification would be widespread and legally mandated, I highly doubt any sufficiently determined 14-17 year old would have any trouble getting past it.
