I am deeply uncomfortable with the implicit premise that children are so different from adults that they should be totally segregated from adults in padded rooms, and furthermore that this is so important that even their parents shouldn't be able to override this concern. In order to make a platform that avoids COPPA, facebook will need to ask for the parents consent. As part of this, they will likely give the parents some degree of insight and control over how their children are interacting with the platform. In my view, this makes nearly any negative part of the platform permissible. Children are expected to develop into adults; the only way this can happen is if we allow them to be exposed to the world of adults. Different parents will be comfortable giving their children different breadth in this regard. I really don't think one parent should be dictating to another how to raise their children. By construction, instagram for children will allow the signatory parents to totally opt-out. That ought to be sufficient.
