The Truth Will Set You Free .....
There been a lot of talk about how facebook spys on you, then reports to the CIA.
So heres some advise that may help, It won't make it totaly safe but it might help.
You will lose all your friends in the process, but if you are paranoid about facebook it might help.
If you intend to close your account first, delete All content first.
Set up a new account. do not give your full name, your home town ect, set all the settings to maximum security, do not be tempted to change settings "so more friends can find you" (they always prompting me to do that), don't add the where you are and who you with info to posts and photos (another case of them wanting you to give them info).
And this is most important, USE A SEPERATE BOWSER for facebook and for facebook only, that way they cant track your internet usage.
Even after all that facebook will still be changeing default settings so they can spy on you, so keep your ear to the ground, and look out for comment from other users about changes. Also check websites like PC world for updates that facebook make,
