cyberstalking

Cyberstalking is the use of the Internet or other electronic means to stalk or harass an individual, a group of individuals, or an organization.

A number of key factors (of cyberstalking) have been identified:

False accusations. Many cyberstalkers try to damage the reputation of their victim and turn other people against them.

Attempts to gather information about the victim. Cyberstalkers may approach their victim's friends, family and work colleagues to obtain personal information.  They often will monitor the victim's online activities and attempt to trace their IP address in an effort to gather more information about their victims.

Encouraging others to harass the victim. Many cyberstalkers try to involve third parties in the harassment. They may claim the victim has harmed the stalker or his/her family in some way, or may post the victim's name and telephone number in order to encourage others to join the pursuit.

False victimization. The cyberstalker will claim that the victim is harassing him/her.
