See that is exactly it. I didn't worry about it because they have absolutely no information on me, other than if someone took a picture of me and posted it somewhere, but nothing I can do about that, but things like that scare me.
Look at Snowden, He told us unbelievable stuff and had to move to Russia. Illegal wiretaps etc, and there was no stink or backlash. I thought for sure there was going to be something. Now we joke about the CIA listening to our phone calls.
Just know I am not the masses, I don't have a facebook account, and I give out as little info as I can get away with.
Funny story though, One time when I did have a facebook (alias) my boss called in sick then facebooked her day of fun all day on facebook. Not sure why she felt she had to call in sick to play hooky, but people are really stupid with facebook.
