"approximately 300,000 Facebook users took an online personality quiz, only to have the app that hosted the quiz harvest data from tens of millions of their "friends.""
Why do people believe such promises? For instance, every request to click a link and take an anonymous survey -- look at the URL. Does it include random numbers to identify the source of the URL? Then don't take it. Ignore it, or if you really want to participate in the survey, trim off all that identify cruft. Takes 5 seconds, which is nothing if you intend to take the survey.
The survey people will claim it's to prevent someone taking the survey multiple times. Easy to solve -- set a cookie, and don't let the survey proceed if the cookie can't be set. Anyone so eager to bias the survey results that they delete cookies, well, that's a vanishingly small number of people. There are more people who will lie or make up answers than who will take the time to delete cookies over and over.
