Re: how about a simpler system
In the land of the unclued, the kid who can get access to porn will have something of a money-making proposition on his hands. Indeed a chap I knew years ago started out upon a long entrepreneurial career renting out printing porn to his classmates, and even learned independently about the wisdom of charging both a deposit and a rental fee (in case of any unwanted deposits).
Teenagers are effectively hard-wired to seek out the company of whichever sex takes their fancy, and in the absence of willing partners, images thereof will do nicely. Teenagers are also not fully mentally mature and are not at all above breaking a few laws for rewards like this, so I would wager that many a playground porn empire will be born this way, and also that Opera Mobile will see a quite staggering increase in market share.
