Are you receiving tons of spam comments on your blog and spend a lot of time filtering them manually? I have recently installed a plugin that has taken care of the spam comments on my blog for ever. The plugin is called Simple CAPTCHA that adds a image based verification to the comments section of a blog. This has helped me a lot and I highly recommend that you also install this plugin on your blog and spend your productive time writing quality posts instead of filtering those nasty spam comments.
Look at the comments section below to see how the image verification looks like after installing this plugin.
