I [Dennis Yu] finally came to this realization: People on Facebook won’t pay for anything. They don’t have credit cards, they don’t want credit cards, and they are not interested in shopping. But you can trick them into doing one of three things:
Download a toolbar: It could be spyware (such as Zango) or something more legitimate, such as Webfetti or Zwinkys.
Give up their email address: You’ve won a “free” camera or perhaps you’ve been selected as a tester for a new Macbook Pro (which you get to keep at the end of the test). Just tell us where you want us to ship it.
Give up their phone number: You took the IQ Quiz, so give us your phone number and we’ll tell you your score. Never mind that you’ll get billed $20 a month or perhaps be tricked into inviting 10 other friends to beat your score.
Don't ever enter your details into Facebook. You will get charged for receiving texts or emails and you won't even know it.
