On the contrary, I should think many hundreds of people have people have drunk the MLM Kool Aid and parted with lump sums under varying degrees of pressure and remorseless salesmanship.
Look through the presentations and webinars and referral targets on the BCN websites: this is what MLM does, it takes a credible idea and remorselessly hypes it up and up to unsuspecting civilians who know nothing about the core subject.
This type of marketing is done to friends, family or strangers; anyone who can be persuaded to part with money and start the referrals cranking in is fair game to Multi level marketers.

These are highly organised, well financed operations undertaken by serial scam promoters and relentlessly pushed by their marketing foot soldiers, all dreaming of getting to the top of the pyramid and milking it before it collapses under its own weight.
