How do I keep my forum free of spam?

    Good read, you have a lot of good content. I have only just scanned your blog. As I get time I will be back for more.

    Keep up the good work.

    Kevin, I really don’t appreciate the way you’re loading up my logs with custom user agent fields.

    It’s SPAMMING!

    Shame on you!

    And what’s the code about?
