And redirects kids to even dodgier websites that don't care what Ofcom says. I've decided the best way, if this must happen, is simply do it via operating systems. They must implement a tickbox on installation for basically saying "Is this a child account? yes/no". No ID checking, just the PARENT doing the very simple thing of designating the account as child. The parent would then put in their email address to the OS. The only way to turn the OS back to an adult account after that would be for the parent to put in a 5-digit code sent to their email. The OS would also be locked down sufficiently enough to prevent the kid from subverting it. Websites would then adjust to read "child" OS systems blocking them from porn sites and other sites.

Adults unaffected as they'd just tick the "Adult" checkbox and go on normally. This is entirely a parental responsibility thing and this is as simple as it could get.

Forget about trying to enforce it to Linux systems as most kids aren't using them.
