While we will never be able to fully stop internet piracy, there is one fact that should reassure those who are scared of internet theft: most people do not give a crap about you.
This past week there was a surge of people who posted a swatch of legalese to their Facebook walls declaring their copyright to their Facebook walls. Unneeded for two reasons: 1) your copyright is implied automatically and 2) nobody wants your photos of your brunch. Honestly, it's all yours.
People who are extra paranoid about their personal data being mined remind me of people who not only believe in past lives, but that they were SOMEONE COOL in a past life. "I was a priest in a past life, someone who guarded secrets," my neighbor Nan would whisper when I collected for my paper route (I assume my collections were some of her few opportunities for conversation). "I still have that power." Nan wore paper shoes, had a living room that smelled like glue and I presume never entertained the notion that in the past life she was someone who sat around wondering who she was in past lives.
Your information is safe, generally, if only because no one is looking for it. The diplomatic name for this strategy is "security through obscurity" and it tends to work well even in real life. For example: over a six month period I once locked myself out of my Brooklyn apartment three different times. To remedy this I 1) made sure a friend had a copy of my keys, 2) kept another copy in my bag and 3) stopped locking my door.
Robbers in New York City come in through windows that are on fire escapes. So I locked and barred that window, but left my apartment door completely unlocked. The front door of the building remained locked, but not my interior front door. Number of robberies over a two year period: zero. Number of times I got in despite forgetting keys: an embarrassing number of times.
