We already have multiple solutions for blocking children from websites that parents don’t want them to access and the companies providing those situations maintain their own databases of different types of content tagged so that parents can have some control over what is blocked and what is not. This stuff has existed since the 90s it’s nothing new. It requires parents taking the initiative though and really when we get down to it this is another, "but think of the children, " sort of situation where they are using child safety as cover for making it easier to collect biometric data of people online.
