Better educated children, less victims?

So many conflicting reports about the influence of internet on children and adults that I do not know if this one must be trusted either. I disagree with the idea that the internet cannot have a negative impact. No later than a week ago, a teenage girl escaped from home and met a man met through msn, paedophile presenting himself as a 16 years old...
on the other hand, the message that on the net you cannot know who the other person is really and that one should be more wary about one's privacy, may start to come through?
