If you ever see an auto-complete feature on a website, it's probable that that website is logging every keystroke. If you type "thermal detonators" into Google, but never actually click the button, it's still flagged up aboard the Imperial Command Ship.
I once read an article about facebook even reporting back to the mothership messages that you typed out but did not actually send because you changed your mind. Never forget: The website owns the window you're operating in (if there's JavaScript), not just requests you send by clicking <a> links.
Doubt it. Remember the NSA "scandal" that lasted a few months before people went back to not caring? Remember Kony 2012? North Korea's human rights violations? You'll never fix the problems in America until you fix the horrifically apathetic attitude of Americans.
