This could have been an http header. It's hard to identify people, but blocking child-locked devices should be easy, since the devices can be built to cooperate.

Then it's up to parents to give their kids child-locked devices and for stores to not sell unlocked devices to kids.

There is just such a HTTP header, for adult sites. It's not granular enough to set individual age ratings, just to mark a page as 18+.

Child-locked devices can already whitelist/blacklist sites and apps. The issue is not capability.

And before anyone blames the parents, parents will always be shitty. They are an impediment to children's health society must work around.

I wish we would just pull the plug on ad-based social media altogether. The incentives add up to destroying society.

People keep saying it’s the parents responsibility to keep their kids safe, and don’t give them the tools! This is such an obvious one. I should be able to lock down a laptop for a child, and then have the browser limit websites to those that are actually child safe. I don’t care if a government agency is the one issuing “child safety certs”. This gets around the whole “identify everyone no matter what” thing, and it means that parents don’t have to run an entire IT department level of security infrastructure to keep their kids safe online.
