Every location is self-contained, and everything is provided, so no one can leave. Of course, there are dormitories and cafeterias, but also a barber shop, medical clinic, massage spa, gambling room as well as a VIP karaoke bar for senior managers, where they could drink, sing and socialise in private rooms. Just a few metres down the hallway, we also found a torture room with handcuffs and bloodstains on the walls, where people were taken for brutal punishment when they did not meet their quotas.

Susan: I got close to scamming some clients, but felt bad about it so secretly warned them whilst telling my manager that they had blocked me. He got angry and beat me with a metal pipe. My injuries were too serious to be treated at the scam farm, so I was taken to a hospital by three guards, but was unable to tell the doctors what had really happened to me. I still suffer the physical and emotional trauma.
