    As a suggestion, if spammer is a bot, then you can add an additional field to your comment form, which is absolute positioned and have something like "left:-2000px" (via css). In this way, it will be not visible to your visitors, but bots will see it and fill it. On the server side, you can check this field to see if is there any data come from it... Rest is up to you, you can just ignore that comment or ban his IP for while.

    If spammer is not a random attacker bot and analyzes your comment form before spamming it, then you can try a more complex captcha system and prevent being commented from same IP in a certain amount of time.

    If you're using WordPress, Akismet plugin is really effective based on my experience.

      May I asked a little longer.
      What questions should we put into that field. Then he will spam it in then?

    I second using Akismet if you are using Wordpress. You can also try enabling options to approve comments before having them published.
