The repeated use of electronic communications to harass or frighten someone, for example by sending threatening e-mails or messages etc is termed as cyber stalking.
It is a crime in which the attacker harasses a victim using electronic communication, such as e-mail, messages, or messages posted to a Web site or a discussion group.
A cyber-stalker depends upon the secrecy managed by the Internet to permit them to stalk their casualty without being identified.
