6 Anti-Spam Plugins for WordPress

Anti SpamSpam is a thing which every high-traffic (even some medium or low-traffic) blogs, forums, websites etc. have to face. In this post, we will discuss some of the best plugins for WordPress which can deal with spam. No, not those based on Captchas or making your users solve math problems, rather we will discuss on some of the new and innovative plugins which work differently, but do the same thing, that of taking out the spam from your blog.


AkismetBy Matt Mullenweg | Download

Akismet is the default plugin bundled with your WordPress software. When a new comment, trackback, or pingback is posted on your blog, Akismet performs hundreds of tests on it and gives a thumbs up or thumbs down.

WP Spam Free


By Scott Allen | Download

Most of the spambots cannot process javascript and cookies. This plugin takes the advantage of this and uses a dynamic combination of javascript and cookies to separate spambots from humans, preventing 99%+ of automated spam.

Bad Behavior

Bad Behavior analyzes the HTTP headers, IP address, and other meta data sent by the visitor and determines if it is a human or a bot. After all, spammers don’t code their bots very well and if they could code very well, they probably wouldn’t be spammers.

WP Captcha Free

By iDope | Download

WP CAPTCHA Free blocks spam on your blog by validating a hash based on time (and some other parameters) using AJAX when the comment is posted. Comments posted via bots will not have a correct hash and will be rejected.


WP Clickcha

By iDope | Download | Demo

Clickcha replaces your post comment button with an image based CAPTCHA that requires the user to click the image in a particular area to solve the puzzle. Clicking the image also submits the comment.WP Clickcha Plugin for WordPress

WP Hashcash

This plugin verifies the users by a piece of javascript code that indicates that the visitor is a real human being, not a spambot. If the javascript check fails, there are three options – it can either put the comment into moderation (default), put the comment in the akismet queue, or delete it.
