I know that it should have been posted earlier but it really went out of my mind.See here’s what you have to do-


You need to have paypal account (if not you can create one for free at paypal.com) and surely most of you are already on facebook.
You get $1 just for adding this app. Then invite your facebook friends and get $1 for each friend upto $100 credited directly to your paypal account.
And yes this is not scam. It is a promotion run directly by paypal in association with facebook.
