Akismet

Akismet Button

Akismet is a spam filtering plugin for blogs. It stands for Automattic Kismet – Automattic is the company which funds the project and also employs most of the WordPress developers. Kismet meaning fate or fortune. I guess that means that Akismet gives spam bloggers what they deserve – no recognition, money or links.

Akismet is built into WordPress version 2 and available for other platforms. A list is here and includes Drupal, Movable Type and Expression Engine. It is free for non-commercial use, which Automattic define as making less than US$500 a month from your blog.

This site doesn’t exactly have the worlds largest readership, but I still manage to get blog comment spam, particularly when I write about money. So when I rebuilt this server about a month ago I went off and registered for Akismet by signing up for a wordpress.com account. Since then Akismet has blocked 110 spam comments from being posted (and deleted) on my blog, including 4 in the last 24 hours.

The way Akismet works: when a new comment, trackback, or pingback comes to your blog it is submitted to the Akismet web service which runs hundreds of tests on the comment and returns a thumbs up or thumbs down. The statistics say that 93% of all comments are spam.

I know Google’s Blogger uses image recognition to block automatic comment posting. Do any of you guys out there get a lot of spam on your sites? What do you do to keep it under control?

  1. For a while, simply having a Preview button first up, then the Submit button after the comment had been previewed used to work fine.

    On my TextPattern site, I didn’t have any problems for a long time, but then the comment spam did increase. I can’t really remember how it was fixed, but I think Neil pointed me to a TxP plugin that did the trick – not Akismet. These days I get no comment spam, although can see the occassional attempt in the log.

    On the church site, Expression Engine is pretty good. I was getting a small number of spam comments, but with the membership facility, they had to be moderated first, meaning they never appeared on the site.

    I’ve since enabled Captcha on the comment form if the person submitting is not a member. That has wiped out any problems. (Although Captcha is not ideal due to accessibility issues). I notice I’ve only got Captcha on the Bible Talks part of the site, not the Blog – not getting any spam at the moment on the Blog without Captcha.

    I do see a lot of garbage being submitted through the search on the church site though. Don’t really see the point of it… It’s only me who sees the search log.

    This has no basis in fact, but it seems that WordPress sites have a bigger problem with comment spam. The simple act of “Preview” before “Submission” on TxP seems to knock out a lot of potential spam.
