That sounds somewhat like what Canada is trying to do. Its bill makes certain types of content unavailable to people under the age of 16.

Canadian kids will be able to access social media, as long as that site has effective means to prevent bullying and similar restrictions.

I doubt any sites are actually going to comply, so it'll be ban in practice.

It would be a ban only to children. "Addictive" sites without certification could still be accessed by those who are no longer their parent's responsibility.
