Cyberbullying involves hostile behavior through technology that is intended to harm others. It differs from traditional bullying in that it allows anonymity, there is no scene of the crime, and victims cannot escape it. Some forms are considered criminal acts under Canadian law if they cause fear, spread defamation or hate, or violate privacy through impersonation. Both active aggressors and passive bystanders can participate in cyberbullying. Prevention involves being careful about sharing personal information online and telling trusted adults about cyberbullying incidents.
