I've been on the receiving end of so many spam comments that I'm going to have ask that anyone leaving a comment (thank you all!) from now on appends a name to it, even if it's a pseudonym. Obviously it would be nice if you left your real name but I totally understand the preference some people have to keep their web presence as quiet as possible.
The bottom line is that I can no longer accept anonymous comments. I'm getting several hundred a week and, since a few bona fide commenters leave anonymous comments, I have to check each one to make sure I don't miss anything. It takes quite a while to do this.
If I know there will be no legitimate comments left anonymously by readers then I can just delete all the spam comments without reading them. I've left a message to that effect on the comments form. Since I can't personally track down and dispatch the spammers, this is my only option. Thanks for your understanding.
