92% of all comments on blogs are spam. Yet you’ve never seen a spam comment on this blog.

I use a free for personal use spam blocker called Akismet:

… Automattic Kismet (Akismet for short) is a collaborative effort to make comment and trackback spam a non-issue and restore innocence to blogging, so you never have to worry about spam again.

Who doesn’t my email spam blocker work properly?
