If you have been hacked - Do you have a facebook page?... If so, have you clicked on a link - usually to something called an "app"... that says something like use facebook log in information (or something to that effect)?....
'Cuz - when you do - THEY GET YOUR INFORMATION!
I NO LONGER fall for that little scam - it happened to me twice..... heckuvit is though, when it comes from one of your friends, you just "believe" it's legit.... none of my friends send that stuff out though.... now, if and when I get one, I generally take a screen shot of the page and send it to the friend and suggest that he or she has been hacked as "he or she" has "sent" this to me.....
Just so as you know how it is possible....
