earn money at facebook????

currently many ppl tell me how to earn money at facebook.but i want all of u think think 1st.facebook really can earn money?????for me ,create the game or other , need the cash to unlock or other thing at tis application,facebook really can earn money. but earn like call ppl join then give rm100,then u intro other join,then u can get back ur rm100.it let me feel like the pyramid .sure the ppl gain more money is the ppl give tis idea.look like the sale one.

i really sacred tis ar.so i plan do the online business,sell the face mask,eye mask .n other lah..but hope tis will work lah. many ppl say do the own business is hard,but for me ,do the business is easy ,hard is how to maintain it,
