It seems strange to me how everyone is deriding this girl, seems that everyone here has forgotten what it is like to be a child and to have that first love or crush. Although most kids are smart (they are not idiots like most people here would have us believe)They tend to be educated, tech savvied and generally clued up, but they are still young, teenagers with emerging hormones, and emotional inexperience.
This girl fell in love, wanted to please her boyfriend, and as MOST teenagers probably felt it was a true love that will last forever, remember that feeling? She would of trusted him, probably trusted him more than her parents. All she is guilty of is being Naïve.
As to the boy, all we have is presumption on his motives, the fact that this image has spread across different schools though does indicate that the boy, or someone he sent the picture too was malicious, and did intend to distribute the picture to a large group of people knowing it would cause distress to the girl, that is who should be really punished.
Putting all these kids on the sex register is rather stupid, I guess everyone just forgets what it is like to be a child, harsh words maybe needed, possibly community service for the more serious offenders, perhaps with some counselling on empathy and human feeling might also help.
But there is just so much hatred on here towards this girl and her mother, people need to get a reality check, kids demand the latest gadgets for Christmas or birthdays, it is the nature of kids, it is the nature of parents to trust their children, it is the nature of children to push the boundaries set to them. I did all sorts when i was a kid, I had interest, curiosity and a desire to know everything and felt I was mature enough and an adult by their age, I wasn't of course but I felt I was, just as these kids will.
Anyway carry on with your bitterness and hatred, I am sure it will help you through life (NOT)
