I am so sick to death about these constant "privacy concerns".
If you have some deep dark secret that you don't want the world to know, then don't go around posting it on a system that bills itself as a way of providing ubiquitous access to everything posted to it!
These people who get concerned about privacy are the digital equivalent of somebody posting a billboard with their contact information, then claiming a violation of their privacy when people use that to contact them!
You posted it online. On a public forum. You cannot expect even a modicum of privacy when you do that. If you have a problem with people reading what you write, don't write it!
