Reduce Spam comments on WordPress blog

There are many plugins and some direct methods to reduce Spam comments on the WP blog. Here I have covered both the aspects of filtering.

#1) Akismet (Automatic Kismet) WordPress plugin 

This plugin comes with every WordPress installation and is a trusted plugin for filtering spams from genuine comments. It checks each and every comment,  ping-backs, and trackbacks submitted in your blog. In order to activate it, you need an API key, which you can get for free by simply signing in Akismet.

#2) Re-CAPTCHA WordPress plugin

This is another effective method to reduce spam but it might reduce the number of your regular comments because most people find it annoying to enter a CAPTCHA for posting comments in a blog. The idea behind Re-CAPTCHAis to display an image with distorted words and ask users to type the word before submitting the comment. This way, spam bots will be prevented to post their comments in your blog.

#3) Mollom WordPress Plugin

This is one of the largest website spam filtering systems which drastically reduces the burden of blog moderation. You can install the Mollom WordPress plugin for free and need to create an account and activate the plugin. Mollom uses Akismet-type spam filtering technique combined with a CAPTCHA to check spam comments.

#4) Close comments on older posts

Older posts that receive good traffic are often the best targets for spammers, so closing comments on older posts is a good strategy to fight spam comments. Just go to Settings -> Discussions. Click on the Automatically close comments on an article older than check-box and enter the number of days. The disadvantage of this method is that your post might miss some useful comments over a long time.

If you find some IP addresses are constantly sending spam comments in your blog posts, you can block those IPs by editing the .htaccess file. First of all, download the .htaccess file from the root directory of your web server, edit the file by adding the list of black-listed IPs as deny from and upload it.
