* A site must be certified by some board in order to be accessible. At what level is a site certified? Root level? Page level? Individual content item.
* A site hosts user generated content. This could be as small as comments on an article, or as large as YouTube. How is the site certified? If each piece of content must be certified, who assumes responsibility for certification?
* A site is certified as appropriate for all ages. The owner of the site then puts content that would have caused to to fail certification. At what interval is a site expected to recertify? What is the ramification for certification and then hosting of objectionable content?
* You have a process that is onerous for site administrators to comply with in order to host content for children. What incentive is for them to comply vs. not host a site that requires certification?
* As a parent, you install a compliant operating system that enforces this system. Sites comply with the program and it works without exception. Kids talk, as they do, and share how to get around this system by using a Linux live environment to boot into an OS that does not enforce the parental control header. How do you prevent this?
* As a parent, you install a compliant operating system that enforces this system. Your kid either does not know how, or is prevented from circumventing these access controls. They have one or more friends that have computers that are not blocked from accessing this content. How do you prevent them from accessing content in this system?
There could be an organization that verifies that the owner and operator of the site are not foreign (so they can be taken to court if needed), reviews the content policy and moderation policy to ensure that no unsafe content can be published, and issues a cryptographic signature to the website. The website displays a signature in HTTP headers.
> How is the site certified? If each piece of content must be certified, who assumes responsibility for certification?
There should be moderation policy guaranteering safety, for example, all comments must be reviewed by moderators.
> The owner of the site then puts content that would have caused to to fail certification
Then they can get into jail if they do it intentionally.
> What incentive is for them to comply vs. not host a site that requires certification?
They can have paid content or show ads.

Requirement to install Linux will stop majority of children.
Basically any site whose owner or operator you cannot put to jail.
.. and then the requirement
.. and then the law?
I'll take my Internet unsafe, thank you very much.
