hi there,i have joined approximately 12 paid to click sites which pay me when i look onto their ads and click..i joined all of these as one of my friends told that i can make extra money with these.but i have on these since 15 days and still in each of them my account has only a few cents and in some not even a sent while their payout limits are in dollars.i read on this forum too about referrals and saw on a few sites that some persons don't click on much ads but are getting paid due to the clicks by their referrals.i mean why can not i get many referrals..is it possible to get them without paying anything?i am really confused because whenever i try to ask anybody to join under me they are already members of that site..can anybody help me out?thank you in advance..
