If you don't want your children to be molested via the internet don't give your children access to the internet, end of story. You'd never let your 10yo child hang out at the skater park because the moment you are not there present someone might abduct him, but letting your child create accounts on every social media imaginable and giving him unfiltered access to the network is somehow acceptable and the rest of the world should suffer because of it?
Children don't need to own smartphones, computers or internet access, just like they don't need to listen to death metal or watch gore movies. Those things will come with time and maturity and your lack of parenting is never going to excuse the government snooping on everything I do
