basically its the rule of many sites that if you get people to join under your link you will get a percentage of their earnings, which i think is fairplay coz the website needs many many members to establish itself so its basically an incentive to get people to join under you and for others to join under them,,,sometimes these can go upto 12 levels deep but commission earnings will get lower and lower...............i had 1 ref but hes inactive now ,he didnt make much difference to my earnings infact was zilch
i am better off with me,myself and i,,,,,,,,,,,,,3 in one referrals ,active daily,guaranteed never to let me down
