Shit with TWO toggles, the other being “is this child under the age of 13?” You could even force sites like YouTube actually to comply with federal law about targeting minors with advertising.
But. These laws aren’t actually about protecting children, they’re about establishing a real identity for every person online.
Amazon! Job cuts! Recession! Scary!!
