The Spanner started to get over 20-30 comment spams per day, I wasn’t happy! I decided to write a Wordpress plugin that would prevent automated comment spam. The Spanner hasn’t had a single comment spam since I installed Spambam.
It works by creating a secret spambam key and storing this in a cookie generated by javascript, the spammer doesn’t execute javascript as they need to directly submit to the wordpress action file otherwise it would slow them down. The plugin is 100% free and I have also created a generic one which can be used by any form/blog.
