I just found something interesting. I had posted a cheapshot as an AC on a thread. Later, I got moderation points; and when I moderate, I browse at level 0. To my utter surprise, I saw that the comment I posted as AC did not have the moderation dropdown box; the other posts did. This leads me to believe that somewhere at/., they keep your ID attached to AC postings.
I wonder what would happen in case of a subpoena or other such judicial order?
