Facebook used to be an easy source to tap into, but since they have formed a public company with shareholders who need to be kept happy, Facebook have changed their Terms of Service several times recently and have clamped down on a number of things that used to make lead generation relatively easy. They have discouraged siphoning off clients to external web sites and CPA offers, and have raised the cost of advertisements that do this. It remains a viable lead source however.
Here is how they mostly work: You sign up and pay the buy-in fee to receive your startup kit, and then you start clogging everyone’s social media feeds about your new venture and beg your friends and family to join you on your “journey to financial success”. You host a bunch of fake parties and wine tastings or worse, you meet up one-on-one to catch up and the whole thing turns out to be nothing more than a demo and sales pitch where you guilt your friends into buying stuff they don’t want or need. After you subject them to that, you then try to recruit them to join your team of consultants, or whatever term your particular MLM uses.
The legal distinction between MLMs and traditional pyramid schemes has been characterized by many authorities as a legal fiction. Jurisdictions that retain a legal distinction between MLM pyramid businesses versus illegal pyramid schemes retain said distinction on two key distinguishing features: 1) that MLMs always encompass the sale of actual products/services, while traditional illegal pyramid schemes ordinarily do not (though sometimes they do), and 2) that climbing an MLM pyramid is overwhelmingly statistically improbable (especially to its highest participant levels) but not theoretically impossible, whereas climbing a traditional illegal pyramid scheme is both statistically and theoretically impossible.
