Information I found intresting and helpful:
National Institute of Justice in Washington conducted a national stalking victimization study in 2009. Victims were asked what they thought motivated their stalkers to pursue them. Of 3,416,460 victims, 36.6% considered stalker motivations as “retaliation, anger or spite,†32.9% replied “control,†and 23.4% said “mental illness or emotional instability.†-http://www.psychologytoday.com/blog/talking-about-trauma/201306/in-the-mind-stalker
The majority of stalkers can be placed under 5 categories:
Rejected Stalker- an individual who has experienced the unwanted end of a close relationship, most likely with a romantic partner, but also with a parent, work associate, or acquaintance. When this stalker’s attempts to reconcile fail, they frequently seekrevenge. The therapeutic focus is usually centered on the stalker ‘falling out of love.’ The individual is counseled on how to move on from an angry preoccupation with the past to the sadness of accepted loss.
Intimacy Stalker- will identifiy a person, often a complete stranger, as their true love and begins to behave as if they are in a relationship with that person. Many intimacy seeking stalkers carry the delusion that their love is reciprocated.The focus of management of intimacy seekers is on the underlying mental disorder coupled with efforts to overcome the social isolation. Intimacy Stalkers tend to be more persistent, most glorify their actions and truly believe they will have their person of intrest
Subtype Stalker- like the intimacy stalker, hopes their behavior would lead to a close relationship, satisfying their need for contact and intimacy. However, this type of stalker acknowledges that their victim is not reciprocating their affection while they still continue their pursuit. I view these stalkers as intellectually limited and socially awkward. Given their inability to comprehend and carry out socially normal and accepted courting rituals, the incompetent stalker uses methods that are often counterproductive and frightening to its person of interest.
Resentful Stalker- experiences feelings of injustice and desires revenge against their victim rather than a relationship. Their behavior reflects their perception that they have been humiliated and treated unfairly, viewing themselves as the victim.
Predatorial Stalker- has no desire for a relationship with their victims, but a sense of power and control. they find pleasure in gathering information about their victim and fantasizing about assaulting them physically, and most frequently sexually.
On average the highest percentage of stalkers fall between the age group of 18-26. The typical "stalk" last 1.8 years on average.
When it comes to gender, women tend to stalk other women significantly more than men. Males on the other hand have a 50/50 chance statistically for either gender. A male stalker, that gets my paranoia going.
I also found a community of stalkers here. I spoke to one about his experiance, he became obsessed with a foreign exchange student from Spain. He only spoke to her for a week, he is still is haunted by his obsession 10 years later.
