As an IRL example. A 14 y/o can find "Adult Movies" on the Internet if they seek for it but also doesnt get exposed to it on his YouTube Frontpage on a on a daily basis.

Instead they'll be put down red pill rabbit holes or, even worse, Spiderman and Elsa pregnancy videos.

Also kids can't read these days so there's no need to worry.
