Of course they're keeping tabs... they've had a telephone and email system in place for over 20 years.
This site amongst thousands of others on the net have been red flagged since their inceptions.
There would be a reader amongst us who pops in from their various other duty sites (after a system message directing them from a word search script dictates) and tabulates the sentiment, and possibly, certain poster's statements.... forwards them to a profiler who either stamps them "bullshit conspiracy theorist from the midwest" or "flag this one/move to their dossier.... keep a quiet eye on them".
Thankfully, we're all too mundane and status quo to bother with... as we'll never amount to anything unless the unfathomable happens and even then, most of us would perish in the reality of what we can only imagine and still won't happen as we'd like to wager by our disjointed and emotionally crippled musings of apocolyptic superpower termination.
But let's face it... I, as I'm sure you all do, enjoy thumbing my/our noses at the machine from a percieved afar. It's a healthy outlet, keeps us in our benevolent best, and personally..... I'm hoping a cushy government job offer comes through my email account
(seriously, my contract is up in 3 months... wise all reading person. Let's do lunch)
