"Network marketing" and "multi-level marketing" (MLM) have been described by author Dominique Xardel as being synonymous, with it being a type of direct selling.[6] Some sources emphasize that multi-level marketing is merely one form of direct selling, rather than being direct selling.[23][24] Other terms that are sometimes used to describe multi-level marketing include "word-of-mouth marketing", "interactive distribution", and "relationship marketing". Critics have argued that the use of these and other different terms and "buzzwords" is an effort to distinguish multi-level marketing from illegal Ponzi schemes, chain letters, and consumer fraud scams.[25]

Influence – John C. Maxwell says that a leadership is influence, nothing more and nothing less. Everything rises and falls on leaderships, so it’s an essential attribute for success.  Influence is also used to effectively and persuasively communicate the virtues of a good product or service, and to get people to say YES!  We also know that at sales.

MLMs have been made illegal in some jurisdictions as a mere variation of the traditional pyramid scheme, including in mainland China.[10][11] In jurisdictions where MLMs have not been made illegal, many illegal pyramid schemes attempt to present themselves as MLM businesses.[7] Given that the overwhelming majority of MLM participants cannot realistically make a net profit, let alone a significant net profit, but instead overwhelmingly operate at net losses, some sources have defined all MLMs as a type of pyramid scheme, even if they have not been made illegal like traditional pyramid schemes through legislative statutes.[4][19][20]
