Privacy is just an illusion in this day and age. Right or wrong it's something we have to accept. I know many Americans do not feel the same way I do about this; but I don't feel that I have anything to hide, so I could care less what "they" know about me and my behaviors.
If you were an employer, wouldn't you find out everything you could about perspective employees? If you're foolish enough to have proof of your mispent youth published on the web when you're attempting to find an adult job, it shows that you're not very responsible IMO.
Oh, and just cause you're paranoid doesn't mean that they're not out to get you.
