Also known as "pyramid sales scheme," these are sales devices whereby a person, upon condition that he makes an investment, is granted by the manufacturer or his representative a right to recruit for profit one or more additional persons who will also be granted such right to recruit upon condition of making similar investments: Provided, That, the profits of the person employing such a plan are derived primarily from the recruitment of other persons into the plan rather than from the sale of consumer products, services and credit: Provided further, That limitation on the number of participants does not change the nature of the plan. (Department Administrative Order No. 8, Sec. 2.1)
