The sentiment behind COPPA is understandable, but the practical logistics never made sense to me. It basically makes every website that has any kind of account feature add a box that says "Are you over 13?" and if you click "No," then you get redirected to a page that says "Sorry you can't use this website" or a search engine.
So it takes about two seconds for a kid to realize, "Hey, if I tell the truth, I can't use this website. But if I lie about my age, I'll get in and nobody'll be the wiser."
Maybe it works for babies, but I'm pretty sure kids are smart enough to figure out how to get past it by the time they're 7 or 8.
This is a general HN policy question.
When I first opened this post it was a link to the Gizmodo article talking about the study. It, in turn, linked to the Endgadget article and the source PDF. Why was this HN post hijacked to remove the Gizmodo, and by extension Endgaget, article(s) and point directly to the PDF instead? Is there no value in the content of those two articles reporting on the study?
