How to Fight Comment Spam on WordPress Blogs

If you have a popular blog at the moment, it is just a matter of time until blog spammers discover it and start bombarding it with comment spam. Unfortunately there is no sure fire way to fight comment spam, even WordPress’ own plug-in, Askimet can go wrong sometimes and let comment spam get in to your blog.

But what can you do to make sure you are avoiding comment spam as much as possible? Here are some tips on how to filter out spam comments and make sure that your WordPress blog appears as neat and clean as possible, containing only relevant and positive comments. Having spam comments can really clutter up your WordPress blog and make an impression that you are not very involved in the blog anyways.

  1. Set up manual moderation
    You can instruct WordPress to hold all comments in the moderation queue until you manually approve them. I know it is a bit of pain, but if used together with Askimet plug-in, there is not going to be many comments left to moderate each day.
  2. Set up spam trigger words
    WordPress does allow you to set up trigger words by which you can get WordPress to put the comments in the spam queue instead of the moderation one. There are different words you will find come up very often in spam comments, like names of enlargement products, medication and xx sites. Make sure you filter these out beforehand.
  3. Members only
    You can also set up WordPress in a way that only members can comment on posts. If you are using a CAPTCHA code it will prevent most of the automatic commenting software to get hold of your WordPress blog. Some spammers actually will register on your site and then submit spam comments, however they can later be deleted and blocked as well.
  4. Captcha code
    You can block some auto commenting software by setting up a captcha code for comments. You can also make sure that you do only let a person comment on one post once. You can also set up the maximum numbers of comments after that you will close comments automatically.
  5. Nofollow links
    The very best way to fight comment spam though is to set up your blog as “nofollow”. Spammers are using advanced programs that do determine if a blog is using nofollow links or not. Most WordPress blogs are set up as nofollow as a default.

Google has already confirmed that it is fighting comment spam by making sure spammers do not benefit from the blog’s traffic in any way. Keep your eyes peeled for new development and tools meanwhile that will make it easier to fight comment spam.
