The National Crime Prevention Council's definition of cyber-bullying is "when the Internet, cell phones or other devices are used to send or post text or images intended to hurt or embarrass another person." 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 cyberbullies 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.
