Getting to the bottom of this one is a little tricky, as there's two very, very different claims about what the Rehabilitation Project Force is. According to the official Scientology Newsroom, the RPF was created in the 1970s, at the request of Sea Org members who had fallen from the good graces of their faith. The RPF was, in theory, a place where they could go to live, work, and reaffirm their dedication to Scientology. It admits that they're going to have to work hard, but testimonies from those that have escaped tell a much darker story.
Leaving Scientology gives a run-down of just what conditions people in an RPF facility face, and it includes working 365 days a year and having no personal freedoms. Paid a pittance, they work eight hours a day, study for five, and have half an hour devoted to each meal and seven hours for sleep, leaving half an hour of so-called "personal time." There's no phones or interactions with each other, and any interaction with outsiders is closely watched by security. Security forces escort their charges between the buildings of the RPF, and breaking any rule results in more time added onto the sentence.
In 2012, reporters in Australia got a look at what went on inside this camp when they talked to Shane Kelsey, who signed his billion-year contract (yes, they're that long) when he was 8 years old, and was sentenced to the 100-hour RPF work weeks when he was just 15. Separated from his parents, Shane's father eventually got police involved when he tried to get his son out of the compound — even then, the boy was escorted by RPF enforcers when he stepped out of the facility. Others describe similar stories and episodes that amount to nothing short of torture conducted by the guards, but the truth of Scientology's prison reform camps remains in the dark.
