Cyberbullying

Cyberbullying is the act of harming or harassing via information technology networks in a repeated and deliberate manner. According to U.S. Legal Definitions, "cyber-bullying could be limited to posting rumors or gossips about a person in the internet bringing about hatred in other’s minds; or it may go to the extent of personally identifying victims and publishing materials severely defaming and humiliating them."

With the increased use of communication technology, cyberbullying has become increasingly common, especially among teenagers. Awareness has also risen, due in part to high-profile cases like the suicide of Tyler Clementi.
