Cyberbullying or cyberharassment is a form of bullying or harassment using electronic means. Cyberbullying and cyberharassment are also known as online bullying. It has become increasingly common, especially among teenagers. Cyberbullying is when someone, typically teens, bully or harass others on the internet, particularly on social media sites. Harmful bullying behavior can include posting rumors, threats, sexual remarks, a victims' personal information, or pejorative labels (i. e. hate speech). Bullying or harassment can be identified by repeated behavior and an intent to harm. Victims may experience lower self-esteem, increased suicidal ideation, and a variety of negative emotional responses, including being scared, frustrated, angry, and depressed.
