Akismet is the technology used by WordPress.com in an attempt to filter spam comments in the blogs they host. The idea is simple:
- The user posts a comment.
- The comment is submitted to akismet.com
- Akismet gives a “thumbs up” or a “thumbs down” and the comment either gets posted or goes to spam.
- The owner of the blog has the chance to revoke the decision, and Akismet “learns” and improves its accuracy.
Of course, the system is not perfect. There have been multiple “false positives” during the life-time of this blog (i.e. valid comments that got flagged as spam). Most of them were non-English comments, so clicking “Not Spam” must have thought Akismet a lot ;)
But what is more alarming to me is that some of my own comments on my own blog were detected as spam. This is annoying and silly. Why do my comments on my blog even go through the spam filter? Would I post spam on my blog?
