Eigentlich unglaublich - selbst wenn man ausgeloggt ist von Facebook kann es nun sein dass Facebook über das tracking cookie trotzdem weiter mitloggt wo man surft und dies dann ohne eigenes Zutun auf die eigene Wall pflanzt.

Scripting News: Facebook is scaring me
Nik Cubrilovic Blog - Logging out of Facebook is not enough

Dave Winer wrote a timely piece this morning about how Facebook is scaring him since the new API allows applications to post status items to your Facebook timeline without a users intervention. It is an extension of Facebook Instant and they call it frictionless sharing. The privacy concern here is that because you no longer have to explicitly opt-in to share an item, you may accidentally share a page or an event that you did not intend others to see.
The advice is to log out of Facebook. But logging out of Facebook only de-authorizes your browser from the web application, a number of cookies (including your account number) are still sent along to all requests to facebook.com. Even if you are logged out, Facebook still knows and can track every page you visit.
