http://www.washingtonpost.com/world...58b5be-34f9-11e3-80c6-7e6dd8d22d8f_story.html Short summary: During a single day last year, the NSA?s Special Source Operations branch collected 444,743 e-mail address books from Yahoo, 105,068 from Hotmail, 82,857 from Facebook, 33,697 from Gmail and 22,881 from unspecified other providers, according to an internal NSA PowerPoint presentation. Those figures, described as a typical daily intake in the document, correspond to a rate of more than 250â€‰million a year. Each day, the presentation said, the NSA collects contacts from an estimated 500,000 buddy lists on live-chat services as well as from the inbox displays of Web-based e-mail accounts. The collection depends on secret arrangements with foreign telecommunications companies or allied intelligence services in control of facilities that direct traffic along the Internet?s main data routes. Key notes: Spam has proven to be a significant problem for the NSA ? clogging databases with information that holds no foreign intelligence value. The majority of all e-mails, one NSA document says, ?are SPAM from ?fake? addresses and never ?delivered? to targets.?
