I am trying to say that information such as your private username, email, Facebook account and even your birthday or worse your email whether private or public can cause problems.
• kill you or find you
• rob you of either your belongings or your reputation
• call the police if they feel the need to even if you did not do anything wrong.
I won't say much more other then be CAREFUL out there: http://safety.lovetoknow.com/Internet_Safety_Adult#u1oXhDkY3sdvGqZ0.97.
Be safe and happy reading!
