These days Akismet’s accuracy have drastically reduced and its not as effective as it was couple of months ago. Akismet was designed to learn from its previous mistakes and keep improving itself, but unfortunately its taking too long to learn.
Worst of all, Akismet doesn’t even notify the commentor that his comment has been marked as spam, so its pretty hard to make out if your comment is marked as spam or kept under moderation. I and some of my friends are facing the same problem, So check your spambox before hitting that delete button.
What can you do to prevent spam?
- Use alternative Spam Filters like Spam Karma (SK2)
- Use Bad Behavior (Thou it doesn’t stop spam, it reduces the rate of spam)
- Use Captcha or Anti Spam Image
Why SK2 is better than Akismet?
SK2 is considered better than Akismet mainly because SK2 doesn’t have a universal blacklist and once if a comment is accidentally marked as spam, demarking it will put the commentor’s IP address in a whitelist, so that it won’t be caught as spam again.
Although Akismet has selflessly served in blocking 19786 spams on TechBuzz, I don’t think its good enough any more, so I’m switching over to Spam Karma 2. I’ve been also considering using Captcha to prevent spam, but TechZ suggested me that, it may hurt my commentators, so I have dropped that idea temporarily.

Great suggestions - I myself was dissatisfied with Akismet, so I downloaded myself a copy of Spam Karma 2 this morning. Also, Capacha works sometimes but hurts your reputation a bit.
Thank you for this post!

Yes Steven, . I think the combination of Bad Behavior and SK2 works very efficiently, but BB isn’t compatible with WP-Cache

I definitely know the feeling with Akismet as it kept catching your comments. It seems okay now, but it’s catching TechZ’s now. Can’t escape it
I’ll be switching over to SK2, as well, sometime.

Nyssa: I used a proxy to leave comments on your blog, else it would have been caught again.

Sindhu: Sorry, I couldn’t save your previous comments. I get around 900 Spams a day and I can’t go through each one of them.

I’ve always used SK2 and BB on my blog.
Never bothered much with Akismet, though I do use it as a plugin for SK2.
