If you have nothing to hide...
Post your full name, address, social security number, date of birth, mothers maiden name and other security questions, list of active logins and passwords and URLs, your full body scan nudes, sexual fantasies, diary/journal, your ashamed moments in your life, sly or trickster things you've done to others, sordid family secrets, and more.
Oh, that was a no? I guess you DO have something to hide.
