I don't even want to think about where my blog would be without Akismet. It comes pre-installed with WordPress but I know there are a good handful of people who delete it right away. "Oh it's made by WordPress and I don't like to do things that are all by one company .. and if I get too much spam I gotta pay .. wah wah wah"
First - you're not going to get THAT much spam - and if you're blog is cool enough to get spammed that much, the price is worth it.
Just check this screenie out:
My measly little site has gotten over 1000 spam comments ... to me that is amazing.
We can’t stand spam.
Who can? You have better things to do with your life than deal with the underbelly of the Internet. 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.
