Cyber bullying involves tormenting, threatening, harassing, humiliating or embarrassing someone using the internet, mobile phones or other digital technologies. It must involve minors on both sides. There are two main types - direct attacks through messages or posting content, and cyber bullying by proxy where someone else does the bullying. Common reasons for cyber bullying include anger, revenge, entertainment or seeking attention. Cyber bullying can negatively impact children and teens through anxiety, depression, withdrawal and emotional distress. Prevention through education is key to addressing this issue. Resources are available to help victims of cyber bullying.
