The definition of cyber-bullying is "when the Internet, mobile phones or other devices are used to send or post text or images intended to hurt or embarrass another person." StopCyberbullying.org, an expert organisation dedicated to Internet safety, security and privacy, defines cyber-bullying as: "a situation when a child or teenager is repeatedly 'tormented, threatened, harassed, humiliated, embarrassed or otherwise targeted' by another child or teenager using text messaging, email, instant messaging or any other type of digital technology." Other researchers use similar language to describe the phenomenon.
Cyber-bullying can be as simple as continuing to send e-mail to someone who has said they want no further contact with the sender, but it may also include threats, sexual remarks, pejorative labels (i.e., hate speech), ganging up on victims by making them the subject of ridicule in forums, and posting false statements as fact aimed at humiliation.
Cyber-bullies may disclose victims' personal data (e.g. real name, address, or workplace/schools) at websites or forums or may pose as the identity of a victim for the purpose of publishing material in their name that defames or ridicules them. Some cyber-bullies may also send threatening and harassing emails and instant messages to the victims, while other post rumors or gossip and instigate others to dislike and gang up on the target.
