For all of you that use facebook, don’t allow an app called “Blu Ray” access to your profile or deactivate it in your settings. Your friends will thank you for not spamming their walls.
Additionally it may be a good idea to check the Reclaim Privacy website for a neat little open-source javascript bookmark that checks your facebook privacy settings for anything that you accidentally share with the whole wide world. The only feature I’m missing at the moment is a photo scanner, but the guys that do the coding are already on it.
