There have been 41 suicides since 2003 involving cyberbullying in the United States, Canada, Australia and the United Kingdom, but most of the victims were also bullied in school and many suffered from mental illness, including depression, said John C. LeBlanc, a professor at Dalhousie University in Halifax who conducted the research.
"Although cyberbullying is a new and fairly awful modern manifestation of bullying … it is not a cause of suicide," he told CBC News. "It's only one factor among many … People who are cyberbullied have, for the most part, been bullied in more traditional manners as well."
