I think Scientology is pretty good at scaring people so they turn against their friends. If that were to happen to me, I'd want a way to signal to my friends that the clams got me and I have to obey them to some degree. But how to do that without tipping off Scientology to my covert message? Finally I think I have found the answer: start acting like Marty. Make outrageous accusations against former allies without dox, be vague, promise that evidence is coming real soon, etc. Then people will know the score.
