When we post content to the web, the users who view the information can usually download the files they see. This means photos, videos or text. Just because you remove the information, does not mean it has been removed from their computers. It is wise to use the rule "would I feel comfortable having this information on the front page of a newspaper or magazine," because your content is just as public!
