Spam is the worst thing that every blogger is worried about. Although there are many spam control plug-ins which help us in controlling spam none of them is 100% reliable here are the best available anti spam plug-ins which I have used and reviewed.

Akismet – This plug-in is developed by Auttomattic Company and it comes inbuilt with WordPress installation. It checks your comments against the Akismet web service to see if they look like spam or not. You need a WordPress.com API key to use it. You can review the spam it catches under “Comments.” To show off your Akismet stats just put <?php akismet_counter(); ?> in your template.

WP-Ban – Most of the Spammers are bots which will comment from a particular IP and WP-Ban is very useful plug-in to avoid comments from particular IP’s and can be used to ban comments based on IP addresses.

WP-Spam Free – Once installed this plug-in will automatically delete comments and thing which I didn’t like in this plug-in is we can’t see the deleted comments.

reCaptcha – I personally hate captcha and at the same time I know that even my readers will hate that, but I hate Spam even more. reCAPTCHA is one of the best captcha plug-in. No doubt this is a great captcha plug-in, but I recommend this plug-in only for those blogs which will get lots of spam comments, as users will lose interest in commenting at your blog if you use captcha at your blog. So use this at your own risk.
