I don't think it's really unfortunate that kids can circumvent technical measures. It's unfortunate that parents want a robot babysitter.

The primary danger comes from breaking the barrier between online and in-person. The best solution seems to me to be parents being understanding and supportive. Want to meet someone you talk to online in person? OK, fine. The parents come along and meet in a public place. If, instead the rule is "no meeting people from the internet ever", teenagers will do it anyway in a much less safe manner.
