That's not what the question was. The man asking the question wasn't technically sophisticated enough to ask about using cookies, and if he were, he would not have asked that question anyway.
The question was, does Facebook collect data on non-users?
What that means is, if I have not signed up for facebook, are you tracking my behavior anyway through the like button and other methods?
- fixermark 9y agoThat, I suppose, would have been a useful question for the Senator to ask. It wasn't the question asked.
- ameister14 9y agoYes, the Congressman's question actually was "Facebook has detailed profiles on people who have never signed up for Facebook. Yes or no?"
- phinnaeus 9y agoDo you mean the like button simply being present on pages or actual clicking of the like button? My understanding is clicking on the like button is pointless unless you're actually signed in to facebook.
- fixermark 9y agoThe like button actually being present means that your client makes a request to FB to fetch the relevant image resources and JS to display the button. When that occurs, FB has some limited ability to get information on your browsing habits based on what that like-button JS is allowed to see of your current session (which given browser fingerprinting techniques, can be enough to unify your behavior with high probability across multiple disparate "blips" of signal).
- kerng 9y agoThe loading of the Like button will give Facebook information about your user agent - it's like a tracking pixel. It's been shown that user agent information together with IP pretty much uniquely identify a user. You dont have to click anything
