The subject of Internet anonymity and children really presents a pest or cholera situation.
No, I don’t want to scan my face or my passport to use the Web. And also no, this glib, thought-terminating, “common sense” quip about “the parents are responsible” is also something to be rejected. We should try to both collectively protect kids and leave adults alone.
Leave it all to the corporations and you would have them prey on your children on every street corner, splash screen, TV menu, and ad board, with no “parental management” option anywhere. “But parents are responsible”, they would say.
