Not the most efficient way to spam, but certainly the most likely outcome. PS: You should make a note that the CAPTCHA is case-sensitive.

The problem comes from people who might come from multiple IPs. Do you trust them? I think the best idea is to find tuples of people (name, mail, IP) who have passed the CAPTCHA once, and then not present it to them again. Unfortunately, that'll require writing PHP code, which I hate, but more importantly, don't have time for right now. I have considered this as well.

Also there are some tricks you can play with your templates to turn spammers away - HTML has more than one way of showing the exact same form, even more using CSS. Make it a little less deterministic and they will leave your blog alone, hopefully.
