Your papers, please! If the forum moderators are tracking IP addresses for no good reason, don't know if I want to post here any more. Innocent posters who want to keep their anonymity intact neither deserve nor warrant having their IP addresses tracked for no legitimate reason. I also wonder whether maintaining such a list violates the terms of service of this website.
The internet gives you an illusion of privacy. In reality it's as if you are walking around with your home address tattooed on your forehead.
It's exactly like asking a real voter for his name and address before they vote. It has nothing to do with guilt or innocence.
