But wait!!!

1) Why do you think there are rating systems for videogames?? Further, why do you think that there are pressures so that selling the wrong rate of videogame to someone on the wrong age bracket gets you time just as much as selling otherwise legal pron, or alcohol or ciggies???

2) Why do you think that every highly-interactive internet site, notably all large socnets, attempts to limit age-blind interaction, either by trying to ban under an age limit, preventing the interaction between those below and above, or many more similar methods??? If it wasn't for such bans, you could organise the Great Preteen Uprising in less than a week in highly-connected countries... (not that I don't fancy the idea of waiting until more countries qualify as highly-connected, myself...)
