> If you do that, social media companies will figure out how to keep kids from accessing their site. Absolutely not. Where do you think 18 year old users will come from? They will come from 17 year old users who turn 18. Therefore, social media sites will still have an incentive to corral kids onto the platform. Because they will one day turn 18 (or 16, or whatever the legislated age cutoff is) and become a source of revenue. Moreover, social media sites want network effects and want to be trendy among young people, even if these things don't directly lead to revenue.
