Teenagers who spend over two hours a day on social network sites are more likely to become victims of cyberbullying, a study has found. The study, published in the journal BMC Public Health, examined data from several European countries.

Researchers at the National and Kapodistrian University of Athens in Greece found that school children in Romania, Germany and Poland were more likely to experience cyberbullying, such as aggressive and threatening messages, spreading rumours and sharing private, inappropriate or humiliating information, if they used social network sites for more than 2 hours a week day.
