Huh?

The question wasn't about how to filter to teenagers, was it?

The question was about what people might want to filter to teenagers.

OK but then we're not talking about the real world where teenagers are able to access anything on the internet (regardless of filtering), but a hypothetical world where adults have total control over teenagers.

I guess what I'm saying is that the premise is false.
