So the bigger your network, the larger will be the sales thus big commissions every week or month. Best part is passive income/residual income. Once you have a big team you get commission from sale made by people u dont even know because they were referred by some 100th guy but u still make money for that sale although your effort was nothing in it. It may sound easy but creating and training  your network takes a lot of time and efforts. THIS IS NOT A GET RICH QUICK SCHEME !!  But if you work hard you can earn money in short period of time u would never earn in jobs.
I think you showed how poor your research is when you tried to claim that MLM’s proper name is referral marketing. I guess Money Magazine got it wrong in 1987? or maybe USA Today did last year: ?
There are many red flags that should warn you away from a business or financial opportunity, but the biggest is a lack of a product. Programs that push recruiting over the sales of a product or service might be a pyramid scheme. If a company isn’t focused on acquiring more customers to buy its products, but rather it's interested in "building a team" or membership of sales reps, consider it a red flag. The foundation of any good MLM business is about getting products and service to end consumers.
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.
Sales agents in MLM companies frequently work for commissions on sales. In addition, MLM agents typically get commissions on the sales of their “downstream.” Sales agents are able to recruit new sales agents into their “downstream,” and those sales agents can recruit new agents as well. An MLM sales agent usually makes money from each sale in their “downstream,” creating a form of passive income.
