Cyberstalking is when the stalker uses the Internet to contact or follow that person. The stalker may make direct contact with that person, they may send nasty messages to that person or spread lies about them to others. Sometimes stalkers use the Internet to learn more about the other person. They might find their address, phone number, workplace or photograph. Then they might use this information to do more stalking or find other ways to hurt that person on the Internet or hurt their body.
