MLM, or multilayer network marketing, is troublesome in the same way a pyramid scheme is because it operates in a network fashion towards its members where the members make a profit out of their own sales as well as recruiting others into the business. They, however, delink themselves from this structure by the virtue of legally emphasizing the existence of real products and services to be sold and not just recruitment. This structure allows them to function legally, as pyramid schemes are illegal because they do not incorporate the selling of a product or service to earn income, rather, they depend on recruitment.
