dryriver writes "The new Facebook advertising policy: 'Our goal is to deliver advertising and other commercial or sponsored content that is valuable to our users and advertisers. In order to help us do that, you agree to the following: You give us permission to use your name, profile picture, content, and information in connection with commercial, sponsored, or related content (such as a brand you like) served or enhanced by us. This means, for example, that you permit a business or other entity to pay us to display your name and/or profile picture with your content or information, without any compensation to you. If you have selected a specific audience for your content or information, we will respect your choice when we use it.' — Facebook also made it clear that the company can use photo recognition software to correctly identify people on the network. It said: 'We are able to suggest that your friend tag you in a picture by scanning and comparing your friend's pictures to information we've put together from your profile pictures and the other photos in which you've been tagged.' — It [Facebook] said it was also clarifying that some of that information reveals details about the device itself such as an IP address, operating system or – surprisingly – a mobile phone number. The Register has asked Facebook to clarify this point as it's not clear from the revised policy wording if a mobile number is scooped up without an individual's knowledge or as a result of it being previously submitted by that person to access some of the company's services. Importantly, Facebookers are not required to cough up their mobile phone number upon registering with the service. At time of writing, Facebook was yet to respond with comment."
