Facebook - the New Face of Evil
I’ve been increasingly irritated with the noise-to-signal ration Facebook creates in my life.
it turns out that protecting yourself from this new attack by trying to leave Facebook is no easy task.
1. The partner site page includes the beacon.js file, sets a <meta> tag with a name, and then calls Facebook.publish_action.
2. Facebook.publish_action builds a query_params object and then passes it to Facebook._send_request.
3. Facebook._send_request dynamically generates an <iframe>which loads the URL http://www.facebook.com/beacon/auth_iframe.php and passes the query_params. At this point, Facebook now knows about the news feed item whether you choose to publish it or not.
just try and leave

My comment is that MSN, Yahoo, and other main chat sites do virtually the same thing as Facebook does, with just about the same amount of privacy, only using different tools. How does anyone get onto the Internet and avoid basic privacy concerns? Facebook only does the same thing openly. Now that subject has been raised, how do you feel about your new attitude concerning the lack of privacy? I happen to disagree with the singling out of Facebook for the lack of privacy.
