You only have to disrupt them enough to make them useless to kids. There needs to be a critical mass of users for the social media tool to work. If some kids get through, fine. Liquor stores sell kids with fake IDs alcohol sometimes. But most kids won't be able to get access making the site more or less useless to those that can. Any large enough mass (someone at a school distributes to lots of people at the school) will likely be detected and destroyed.
