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]
