As the law says I must, this post serves as official notice to my cyber terrorist to leave me and my family alone. I have already contacted an attourney, and will pursue legal action against you if you continue to harass me or anyone else related to me, either by blood or by friendship.

What is cyberstalking and what is cyberharassment?
Cyberstalking and cyberharassment are very similar. Most people use them interchangeably, but there is a subtle distinction, typically relating to the perpetrator's intent and the original motivation for their behavior.

While the two situations usually involve many of the same online tactics, cyberstalking is almost always characterized by the stalker relentlessly pursuing his\her victim online and is much more likely to include some form of offline attack, as well. This offline aspect makes it a more serious situation as it can easily lead to dangerous physical contact, if the victim's location is known.

Why do people cyberstalk or cyberharass others?
Cyberstalkers are often driven by revenge, hate, anger, jealousy, obsession and mental illness. While a cyberharasser may be motivated by some of these same feelings, often the harassment is driven by the desire to frighten or embarrass the harassment victim.

Sometimes the harasser intends to teach the victim a lesson in netiquette or political correctness (from the harasser's point of view). Often the cyberharassment victim is merely in the wrong place at the wrong time, or has made a comment or expressed an opinion that the cyberharasser dislikes. We have even seen cases where the victim is merely being targeted because they are the first ones the cyberharasser encounters when they are in a bad mood.

What do cyberstalkers/harassers do when the stalk or harass someoneThe harasser may post comments intended to cause distress to the victim, or make them the subject of harassment by others.

Harassment
Stalking on or offline involves "harassment". We can summarize "harassment" by quoting from two US State Statutes - one from California and one from Michigan:
California defines Harassment as: ...a knowing and willful course of conduct directed at a specific person that seriously alarms, annoys, torments, or terrorizes the person, and that serves no legitimate purpose. This course of conduct must be such as would cause a reasonable person to suffer substantial emotional distress, and must actually cause substantial emotional distress to the person.

While Michigan defines Harassment as: ...conduct directed toward a victim that includes, but is not limited to, repeated or continuing unconsented contact, that would cause a reasonable individual to suffer emotional distress, and that actually causes the victim to suffer emotional distress.

Malice
Malice means: the desire and intention to terrorize and hurt you. Much cyberstalking is malicious in nature. Malice is usually indicated by the presence and communication of clear and direct threats made against you by the harasser.

Premeditation
Premeditation means: the presence of planning and organization.

Repetition
Repetition means: the harassment is not just a single isolated incident.
Repetition is a key feature of online stalking. A one off attack online, while it may cause you distress, could not be described as cyberstalking. Cyberstalking is a course of conduct that takes place over a period of time and involves repeated attempts to cause you distress. Some laws even define it as involving two or more incidents and following a repetitive pattern.

Distress
Distress means: the activity causes fear and distress to you the target.

Obsession
Obsession means: the stalker cannot stop, despite warnings.

Vendetta
Vendetta means: the stalker seeks revenge against you.

Hate vendettas are a common cause of harassment online. Stalkers and harassers often convince themselves that you have deserved their hostile attention and that they are in the right. They often persuade themselves that you have committed a great wrong and that they are in the position of avenger, punishing you for your crimes. Revenge may be sought for no reasonable offense at all.

No Legitimate Purpose
No legitimate purpose means: the harassment has no valid purpose, other than to terrorize you and cause you distress.

Some stalkers persuade themselves that they have just cause to harass you, usually on the grounds that you deserve to be punished for some wrong they claim you have committed. Other stalkers have no announced purpose other than to make you suffer. In either case the stalking serves no legitimate purpose.

Personally Directed
Personal means: the harassment is directed at YOU personally.
