Yes, sadly, it's true, I've had to disable comments on my blog, as Typepad, the for-a-fee blog service I use, has no mechanisms for blocking robots from posting comments to its blogs, and my blog has recently been hit with dozens of fake, porno comments with links to their sites (in an attempt to boost those sites Google rankings, I suppose). I've been deleting them each by hand, but now I've had enough (about 15 of them today), so until Typead ads some anti-comment-spam features, I'm keeping comments disabled (sorry!)
