Don't know how long ago you went to school, but at least in Australia, every student is provided a personal laptop for school work which is capable of connecting to social media. Maybe you could block it on your home wifi, but that't a step beyond what most people are capable of. And you'd be an extremely unpopular parent if you were the only one blocking social media while every other kid continues to arrange event invites on Facebook Blocking it at the service level would be significantly more effective and mean all kids would have to socialise and send using IM platforms instead.
