The number of comments that have gotten through the Ironclad CAPTCHA since I installed it yesterday but been caught by Akismet is significantly higher than the number that slipped past SI CAPTCHA. I suppose I could do away with the CAPTCHA altogether, but then I’d have to wade through the Akismet queue on a regular basis.

So, I’ve switched back to SI CAPTCHA while I look for something more effective. There are some picture-based CAPTCHAs that require the user to pick a specific image out of a collection of  images. One is Confident CAPTCHA, which has an online demo. It requires the user to pick several images in the correct order to prove you’re not a ’bot. The problem I can see with it is that it’s too much of an inconvenience and requires a user to spend longer than they’d probably want to to pass the CAPTCHA.

So the search for a more effective CAPTCHA continues.

In the mean time, I leave you with this thought: All spammers must die.
