I highly doubt Google is filtering stuff out for the NSA.
   The simpler explanation is that Google Alerts is [1]100% brokenbecause
   it makes Google no money and doesn't do much for their core business
   interests. For my own alerts, it's been sending me results from 2007,
   2009, 2010, 2011, 2012 in random order, over and over, repeating
   results, for many moons now. I've switched to using [2]Talkwalker
   instead.

     sometime over the past few weeks google alerts has started filtering
     (certain?) NSA codewords from alert matches.
     ah well, nice while it lasted...
