Online advertisers are selling you out
Data mining companies like Rapleaf exist to build profiles of Web surfers. They know more than you think -- or privacy policies allow -- and it's high time for this data siphoning to end

Big Brother is watching. And he wants to sell you toothpaste and get you to vote for the candidate of his choice.
The Wall Street Journal's Emily Steel has an excellent piece today detailing just how much Internet data mining firms know about you. The answer? A lot more than you realize. Like: your political affiliations, religious activities, income level, various likes and interests, and your activity on online dating sites, to name but a few. online.wsj.com/article/SB10001424052702304410504575560243259416072.html
And though they claim to be collecting this data without tying it to you personally, it turns out this information is not so anonymous after all.
Today's WSJ story is all about Rapleaf, one of the companies that benefitted from Facebook's latest "inadvertent" data leak, where it received personally identifiable information for people who clicked on advertisements inside Facebook apps.
Rapleaf builds profiles of Web surfers by dropping tracking cookies on its clients' websites, then matching the email addresses of registered users to data it has scraped from social networking sites. Rapleaf then sells this information to companies that want to target ads. This election year, Rapleaf's clients also include at least 10 political campaigns.
