Multi-level marketing (simplified Chinese: 传销; traditional Chinese: 傳銷; pinyin: chuán xiāo) was first introduced to China by American, Taiwanese, and Japanese companies following the Chinese economic reform of 1978. This rise in multi-level marketing's popularity coincided with economic uncertainty and a new shift towards individual consumerism. Multi-level marketing was banned on the mainland by the government in 1998, citing social, economic, and taxation issues.[62] Further regulation "Prohibition of Chuanxiao" (where MLM is a type of Chuanxiao was enacted in 2005, clause 3 of Chapter 2 of the regulation states having downlines is illegal.[11] O'Regan wrote 'With this regulation China makes clear that while Direct Sales is permitted in the mainland, Multi-Level Marketing is not'.[10]

Fast forward to 2017. LuLaRoe is the biggest MLM for women. “More than 80,000 women have paid around $5,000 for several boxes of low-cost clothing and worked as much as 80-hour weeks to outfit hundreds of thousands of suburban women in multicolored polyester. But according to a report that studied the business models of 350 MLMs, published on the Federal Trade Commission’s website, 99% of people who join multilevel-marketing companies lose money. Depending on how you look at it, it’s either a brilliant business model or a predatory practice — or a little bit of both.” (FTC)
Bought MLM leads are still not going to be laydown sales, you WILL still need to talk to them, qualify them and move them along in the process. When  you receive the email that you have a new lead in, call them and ask them how you can help, if they are nasty or negative, just get off the phone. Never, whether you bought the lead or not, try to convert someone who is nasty or negative, it just is not worth your time.
Where can I buy business opportunity leads? That is a question I get all the time from my team and from other people wanting to have success in network marketing. I strongly encourage learning online attraction marketing but the fact of the matter is, it takes time. This article will help you with understanding what to know before you consider buying business opportunity leads.
I agree with you that much of the industry is flawed, but what about an MLM that has a service rather than a product such as electricity. It’s not like that could go out of style or that once you buy it you don’t need it again or that your monthly supply is too much and you’re going to stop the monthly subscriptions. I can honestly say that I cannot stand most MLM companies because regardless what you believe or how much you like the product, if you have to try to convince someone else to use it then inevitably the system is flawed and eventually your residuals will dry up. Electricity though, that’s different in my opinion, no one has to convince me to use it, it just comes by default. Find me an MLM that is not selling so much as showing someone an alternative to what they already have to pay and I’d be interested.
