Really? They're advertising this on the radio now, are they? That
is interesting.
This one ("incomeathome.com") is a sort of "double funded proposal" - it's not just a funded proposal for a network marketing company: it's essentially a funded proposal for a funded proposal for a network marketing company! A curiosity, if nothing else: I can't actually think of another one at all.
I once looked at the "end-company" (Wealth Masters International) myself. It was no use to me because the entry-level product (about $1,500 or $1,600 as I remember - this was a couple of years ago) and I believe parts of the higher-level products are really exclusively American in content (i.e. financial advice about US company law, tax law, and so on). But I certainly didn't see anything terribly off-putting about it, and I know some people do very well with it.
I'm not quite sure it's
strictly "MLM" (though I note the article you've linked to describes it as that, which surprised me a little), but it's certainly network marketing, anyway.
