Now if you enter poal for instance,and don't take a crapton of security measures,pretty much anyone who wants to know will know. Your name,your ip,your address, your phone number,your picture. All it takes is for 1 of them to know something about you, they can then correlate the data,mine for it. You don't need to have a facebook account to have a virtual facebook account. Know what you have to do? Appear in a couple of pictures that your friends post on facebook.
