What do stalkers do/ know about the person or people they stalk?

It depends on the stalker and why they are doing the stalking.





They'd be following their victim around both in the real world and now days also online. Some take pictures or make notes others just follow. Some will harass their victim in different ways. Phone calls, mails, emails, text messages ... and so on. They could also create problems by using their knowledge of their victim to order things, apply for different things (classes and such) or send messages in their victims name. They could find ways to gain access to the victims home, workplace and other places where the victim hangs out. They could also try to befriend the friends of the victim to gain even more information about the victim.





How much they know all depends on how fanatic they are and why they do the stalking in the first place. If they do it simply because they get a thrill out of following their victim around they'll know less that if they stalk because they have a deeper emotional interest in the victim.
