Cyber stalking Cyber stalking is a new form of internet crime in our society when a person is pursued or followed online.

Cyber stalking uses the internet or any other electronic means and is different from offline stalking, but is usually accompanied by it.

Most victims of this crime are women who are stalked by men and children who are stalked by adult predators and pedophiles. Cyber stalkers thrive on inexperienced web users who are not well aware of netiquette and the rules of internet safety.
