Wow! Finally, a way to combat comment spammers that seems it will work! I found this excellent comment verification code on Jeff Barr's blog. Instead of the type-in-a-name method, I went with the simpler checkbox next to the phrase "I am not a spammer." Simple to implement and easy to use for readers. Yay!
