So what exactly do you have to hide?
Just kidding (more or less) but really, what difference does it make. If NSA (or any other powers that be) wants to "get you", does it matter if they have "real data" they sniffed from one of your digital systems or not? If they truly want to arrest/harass/make you disappear whether they have real data or fudged data is rather moot.
So why worry? Either you're below their radar, and they can collect or not your precious data, or you're a target, in which case no matter what you do/hide/avoid won't help you in the long run.
Privacy went out the door along with all those AOL CD's - what's amazing is that people are just starting to notice (or care).
