Exactly, a good friend of mine in college was recommended for a job at the NSA by one of my professors in early 2001. He went to having a heavy online presence and being a constant in our social circles to completely disappearing. His personal site went dormant, he stopped showing up on irc, abruptly dumped his long time girlfriend. My roommate bumped into the guy at a grocery store in Virginia but other than that he doesn't exist to anyone who knew him for years or online.
