Cyberbullying or friendly joke?

A girl, whose name wont be released due to the fact she a minor, Has been harassing her so called friends with mean names and pictures. And the county are deciding whether or not to charge her as her friends say its fine and she does it all the time. This happens all over there school apparently which has caused the stank baldheaded teachers at the school to look over this problem instead of fix it. Since we cant release the girls name the parents allowed us to show a picture to teach the girl a lesson even though her fate is still being decided.
