We're publishing using WordPress, and we've had great success with Akismet for spam-comment filtering. But a handful of spam comments slip through each day, and I worry about the implications of having close to 60,000 comments in our database (even though 99.9% of them are tagged as spam). At this rate/capacity I fear we're taxing the limits of what WordPress was designed to handle.
I've shied away from Captcha and other verification methods in the past, because I don't want to put up any barriers for our readers to comment. But I'm sick to death of dealing with the spam comments, and I realize more and more that nearly every site where I comment has some form of user validation in place. Maybe my readers won't balk as much as I fear?
I'd love to hear from any of you who've added Captcha to your site about how it affected your (legitimate) comment rates. And also, any Captcha alternatives that you've used and liked -- I know I've seen sites that ask commenters to enter a simple check-phrase, but I can't seem to remember where.
