In case you’re still lost as to what the heck is going on, a Scientology Run is when people film themselves charging into a Church of Scientology building to see how far they can get before being caught and booted out. It’s a notoriously secretive religion, so it turns the whole place into an action-movie set piece where the protagonist is trying to infiltrate a compound while fending off its legion of foot soldiers, clad in terrifying white button-ups with black vests.
The hallmarks of cults is: separation from friends or family, a person or ruling body that delivers the one and true version, punishment for rule breaking, and a difficulty separating. Also, it almost always devolves into sex slavery and/or arranged unions.
Those things give you control of course, but they are the basic guidelines of cult like behaviour.
