I’ve recently seen a sharp increase in spam comments which are getting past the Akismet filter. I may need to take defensive action if it keeps up, such as moderating comments or using some kind of CAPTCHA. Please let me know if you have any suggestions. I don’t like anything that impedes the flow of legitimate comments, but I imagine that spam comments are just as annoying to you as they are to me.

As for fun and original CAPTCHAs, this sounds like something Luis Von Ahn or his students might/should be working on. Not that more of us can’t play too.
You should know that there have been a couple of workshops on this topic. See http://www.cse.lehigh.edu/prr/HIP05/ for one organized by my colleagues.
Brian, thanks for the link! Of course, my more immediate mundane concern is how much that work has translated into easily installed WordPress plug-ins. But I’m intrigued by the research and will check it out.
