I used to know a lot of developmentally disabled adults whose viewing habits would be indistinguishable from a ten-year-olds. Wonder how long before a disability challenge comes out; I don't know what Canada's disability laws are, but this would attract the interest of an enterprising lawyer under the US's ADA.

I also wonder if this wouldn't just encourage kids to start mixing adult content into their feeds, which would kinda be a perverse outcome for a law designed to protect children.
