As many have discovered, when you delete your photos from facebook, they are not really deleted. They are just no longer in your profile but they still remain in facebook databases and are sometimes used for ads and such. According to new sources (article here) when you delete your photos they are only used by facebook for 30 days and then deleted. While I am happy they are actually deleted, I need to ask myself, why does facebook need to use them? Should we all stop using this service due to their weird privacy rules?
