FWIW, I'm (very gratefully) a member of the Church being mentioned here (more in my profile link, no product sales or JS at my simple site, but I explain why I am a believer in some I hope skimmable detail), and I have precisely 0.00 interest in MLMs.
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.
