"F . . . the restraining order, she's dead," a pregnant 16-year-old student in Geelong posted on Facebook after she was arrested Wednesday.

The girl, who remains unnamed for being a minor, spent a night in custody after her arrest. A magistrate said Thursday the pregnant teen is risking jail time with her demeanor, Daily Telegraph reported.

The Children's Court has heard the case of the 16-year-old, who had been stalking and intimidating her 17-year-old victim since May. She would drive past her victim's house, follow her in the street, and talk about her at school. Police had warned her about her behaviour.

The girl pleaded guilty to six charges, which included stalking and making threats to kill. She was released on bail, and sentencing was deferred until October for a Youth Justice report.

Bullying remains a persistent problem among the youth, with some victims resorting to suicide to put a stop to their horrible experience.

Cyberbullying, known as verbal bullying in social networks, is only one of the many forms of aggression that kids subject other kids to for varying reasons.

At an Auckland university seminar, NetSafe research manager John Fenaughty noted almost one in five teenagers had experienced cyber bullying. Further, fifty-eight per cent of cyberbullying victims were girls.

Dutch academic Simone van der Hof explained to teachers who attended the seminar that bullying today involves a much wider audience. The bullies are not just in the school vicinity. They virtually enter their victims' homes now, she noted.

In January, a young girl died of suicide a week before her 15th birthday. Friends claimed cyberbullying has gotten into Sheniz Erkan. His brother spoke on Australian radio to appeal to the parents.

"Parents need to keep more track of Facebook and the internet... There are problems that they might not know about that are being kept online... These days there is so much technology and cyber stuff going on it's like a whole other world," Aykut Erkan told 3AW.

"Ensure young people are capable of using the technology, but also know how to keep themselves safe," Mr Fenaughty said.
