Securing and ensuring that our information isn't leaked should be so that others don't use It against us. It's never a defense mechanism that we should adopt just because we are fraudulent.
Maybe you have a totally different understanding of my post.
Every website out there promises your data or information protected including this forum but in the privacy page they advice you to be the first person to protect yourself.
In the aspect you are talking about, what it means is that outside this forum if you happen to be a target or in a criminal related activities and the world is in quest of you, if they can't find your information else where they can come here and request from the admin just to track you down. This part is where you must keep yourself safe first, you may not be the criminal but stolen details can be used and then you get involved in what you don't know hence you're now a target will be given out without much consideration.
