I’ve noticed a large spike in botnet comment-spam. I’ve gotten hit both here, and at the Centresource Blog, and I’ve noticed an increase in spam on Nashville’s Metblog as well.

I wanted to see how it compared to past levels of comment-spam attempts. I wrote a quick little script to scratch an itch in this regard to help me visualize the data.

Behold, comment spam attempts since February 2005 by day. It’s a rather wide image, so that you can get a more refined feel for it. That’s a lot of spam attempts.
