.... Sure there is a risk to having such an account that you will be dumb enough to fly off to the Middle East to me with some guy, but most people aren't that dumb. And most people that dumb probably can't afford to do that, anyway...
However, the point isn't anything about the Middle East, it's about the 40-year-old sociopath who doesn't govern his own sex life with any kind of morality, just what he wants, and that young girls (and boys) are "hot", and that he wants. He has no compunctions about using a phony name, weaseling his way on "friend" lists with a phony persona, saying he's sixteen and lonely, and posting the picture of a "hot" young boy, purporting to be his picture. Teens are notoriously lacking in good judgement or proper suspicion when playing "The Mating Game", which they're just learning, and anybody can afford to walk six blocks (or whatever), or even invite a "friend" to their house when their parents aren't home. MySpace is notorious for attracting those predators.
.... My opinon? I think casting sinners out of the school makes less sense than keeping them and calling them to repentance. The student will be uplifted by the school's good influence on him/her. If they are bringing others down with their bad influence, that's when they should be removed.
.... preach about the dangers of myspace...
Again, it isn't about the kids being "sinners", it's about protecting them from the sinners/predators, and cyberspace extends from school to home and back and far beyond, to "Sin City" or the "Red Light District".
I think that schools do have a responsibility to protect all who are enrolled there, including chasing away the pervert who is hanging around just outside the playground fence, technically off school grounds, and looking, offering "candy" through the fence. Or maybe building a high stone wall around the playground. (Metaphorical, of course, but teens are only a little more experienced than the young enticed by candy, and they have the added liability of their own mating game hormones).
Preaching about the dangers of drowning doesn't work, on a hot summer day with a glittering swimming pool in sight. "Believing" that you're a good swimmer doesn't make it so.
It is better to keep silent and be thought a fool, than to open one's mouth and remove all doubt.
