Paranoia much? Maybe if you want to do illegal things, then turn off all of your electronics.
If you think that videos of kids playing in the back yard are ending up on kiddie-porn sites from hacked cams, you need to turn off the computer and go outside and get some fresh air.
If someone wants to get off from the audio file of me and my wife having sex, more power to them. However, they probably never heard of this place called PornHub. It has a lot more offerings that are way better to choose from.

Personally, I don't care if some bored NSA agent is monitoring my stuff, he's not going to find anything, just like with with every other Average Joes out there.

Hey, here's one for you: The NSA actually owns the entire tinfoil industry, that's how they pay for many of their secret off-book operations. It has to be true, I heard Alax Jones and Joe Rogan talking about it.
