Getting to know your friends

This privacy issue was reported back in December. It is about Facebook and its friend status. In general, it should not be possible to see information about another unknown person, when this person did not configure his/her page to do so. However, there was this issue, that you could send a friend request to this person, waiting for confirmation.

The issue was, that even without the person accepting the friend request, the "is now friends with" status message of this person was updated. Thus, it was possible to track a person's friends without their permission.
