Bad Behaviour plugin is a must for any serious blogger - blog spam is everywhere and without effective protection a blog can be easily overrun by spam (comment and trackback spam).

I have used the bad behavour plugin on a number of blogs (that excepts comments and trackbacks) without any problems. Bad Behavour has blocked hundreds of spam comments and is used on the Portagemma website also.

Plugin website: Bad Behaviour

Version 2 has been released.
