JWs and MLMs are an interesting sociological phenomenon.
You have the least educated group of people in the country (by religious affiliation) who are kept busy during all, or most, of their free time with “the ministry,” both of a which make it difficult for the majority of JWs to earn a decent living. So naturally they are ripe for this kind of scam because they need to earn more than they do, and they’re not educated enough to recognize the futility of any “get-rich-quick” schemes.
But it gets better. JWs are not supposed to “conduct business” at the Kingdom Hall and are discouraged from having relationships with “worldly people.” So who will be their customers?
JWs are easy targets for getting involved in questionable business dealings which have little chance to succeed.
It’s just a recipe for frustration!
