I'm guessing you also believe that "gang stalking" is a thing:

There are people with information that no one wants leaked because the information is incriminating without proper context or someone may have made a massive mistake and not known what the consequences were at the time. There are people all over the place that have to make decisions where both choices might be illegal.
There are powerful CEOs and politicians who are afraid of being outed for not being what they say they are. Some of them are simply paranoid that they will be outed as incompetent. You'd be shocked at how many CEOs are terrified of people finding out they just got lucky and applied for the right jobs at the right times. They walk around in complete and total fear that someone will find out they don't know a single thing about how their company is run or that they are banging half the people in their company.
There are startups that are essentially cults and the founders use cult tactics in order to keep an entourage of employees who are loyal to the point that they will sacrifice their dignity and personal safety for the company. If you don't believe in the founder and the company they purge you because they are afraid someone is going to figure out their business may border on illegality. These guys do the same thing, their employees run around harassing anyone who doesn't believe in their company and the founder.
This happens all the time.
Gang stalking is a real thing, when I was a child people used to call each other up to and gang stalk anyone who had just moved into the neighborhood just for shits and giggles.
It was just a bunch of kids who would call their next door neighbor to let them know someone we didn't know was walking around. The game was to walk outside of your house and just stare at the person as closely as possible as they walked by and then walk back in. Individually its not a big deal but when you walk through a neighborhood and hundreds of people walk out of their home one at a time just to stare at you and they never say a word it makes the person walking around hyper paranoid.
People do this sort of crap all the time for many reasons including extortion, they text message networks of people to follow an individual person around as part of targeted harassment. If the person doesn't pay up in the form of shopping at the right places they just keep following the person around. It's illegal but hard as fuck to prove.
