Taggart 
It was my job for a decade to try to keep tweens and teens safe online. Let me tell you what you already know: no law or technology can do it. There are no lengths kids won't go to to talk to friends without prying eyes. The harder you try to lock it down, the dodgier their solutions will be.

The only things one can do is:
- Create a safe "bright field" (with good & safe platforms instead of #AntisocialMedia!)
- Be good parents/guardiens/friends they can #trust and seek #advice if not help from.
- Teach them #TechLiteracy and #MediaLiteracy.
Anything else (espechally #Prohibition - #Politricks) are an insult to the intellect of #teens
- and complete denial of the fact that they are cleverer, have more time and skill on hand than 99,95% of all adults.
