essentially 2 types of gangstalking, legitimate and schizo delusions.
Legitimate gangstalking is typically done by government organizations on former criminals, or people in the middle of investigation. Its an FBI tactic, they essentially hire actors to follow a suspect around and fuck with them to throw off their mind and cause them to make a mistake. These actors will do things like follow you, bump into you 'accidently', strike up strange conversation, or even do things whilst youre in your vehicle, like cutting you off or hitting your bumper. All of this is part of their scheme to make the suspect suspicious of everything around them so they make a mistake. 
Schizo delusions are when someone believe such a scenario as I said above is happening to them, when it isn't, they're imagining it. Theres also a lot of people who larp either as victims or as the 'actors' I mentioned.
