It's the parents' jobs to know what their kiddies are doing on the computer.
If I had a cute little underaged son I would be proud as punch to know he was chatting with the likes of Phantom2, jrb_actor, Vish, VoiceAnth, Dame, Sueleen and all the rest of all y'all. Maybe he could even go to the prom with Broadway11. Not all parents are as supportive. Crazy, huh?
One way or the other, it's not the government's job to monitor these things.
Stop worrying about what I'm doing -- focus instead on what you're eating.
