I just read the following:
This caused huge amounts of unimportant information to flow through the NSA's systems, according to a chart in a top secret NSA presentation. Every day from Sept. 11, 2011 to Sept. 24, 2011, the NSA collected somewhere between 2 GB and 117 GB of data concerning this Iranian address. The exact numbers aren't clear because details of the chart have been redacted.
This weekend The Wall Street Journal reported additional details: Its story suggested NSA analysts broke the rules to read their love interests’ e-mails and other communications often enough that the behavior was given a nickname — LOVEINT. (The intelligence community tends to attach -INT to their intelligence monikers. Information gleaned from people, for example, is called HUMINT.)
Look at this photo of the massive new NSA "data" center in Utah. A data center is where they keep information the NSA obtained by spying on us.
