But yes, if you're the sort of person who consciously joins a niche religion in adulthood, you're probably the same sort of person who will believe other pitches.
Edit: A few times in my life someone has given me a pitch, someone I knew, but it never seemed to use "position" as leverage, and there are policies against such things I've heard announced at various times, like an ongoing policy against using membership lists for marketing, buildings for business ventures, etc. But it's not surprising that if someone joins such a business they are asked to pitch to those they know.
