I just discovered this.
Every Phone number in your mobile phones, contacts are now on Facebook. They were kind enough to snake them from your mobile phone. (I don’t remember asking for my permission. Oh that’s right when you are a tool of Satan you don’t have to.)
To fix this;
Go to top right of screen, click ACCOUNT, click EDIT FRIENDS, on the left side of screen click CONTACTS.
TO REMOVE, go to the right column and, click on “THIS PAGE” and then you’ll be able to REMOVE the numbers Facebook so kindly took without your permission.
One more reason to switch to Google+
