You apparently earn money for every spam mail you read(Note: You cannot recieve the money until you accumulate $25 worth atleast) and people you refer. I am going to try it out with a specialy made email address and read all the spam I can. Take my refferal to the pyramid.
Note: Use a specialy made email address for spam then use your real paypal account to receive payment.
I have always like to read my spam, why not get paid to do it? :) If this is acctually legit then it would be pretty cool for those who don't skip an email.
