There was a guy in one of my undergrad classes 50 years ago who told us how he started in on it then had second thoughts after a couple of months, mostly because of how creepily dead set they seemed on extracting every dollar he had.
He related how they camped on his doorstep & followed him around for months, and that he still got shit in the mail, and phone calls. He finished by saying, "If those people approach you, man, run. Run away and don’t look back."
Years later after I divorced and was visiting my young children and saw some of their pamphlets in my ex’s apartment I said, "Listen, do what you want, but you know how I’m buying winter clothing etc. and taking the boys on fun excursions and paying for shit in addition to paying my mandated support? If you get involved in that shit, well I’ll continue to do what the law requires but will be it.” Thankfully she never got beyond the pamphlets, which where such transparent bullshit, "road to total freedom" and all. She’s always been a woo-woo so it made sense she’d be attracted to it.
