One of the oldest and the most popular plugin, not just in it’s category but also overall in WordPress. Akismet checks your comments against the Akismet Web service to see if they look like spam or not and lets you review the spam it catches under your blog’s “Comments” admin screen. You’ll need an Akismet.com API key to use it. Keys are free for personal blogs and paid subscriptions are available for businesses and commercial sites.

  •  Automatically checks all comments and filters out the ones that look like spam.
  • Each comment has a status history, so you can easily see which comments were caught or cleared by Akismet and which were spammed or unspammed by a moderator.
  • URLs are shown in the comment body to reveal hidden or misleading links.
  • Moderators can see the number of approved comments for each user.
  • A discard feature that outright blocks the worst spam, saving you disk space and speeding up your site.

  • No false positives due to the method of spam blocking, which leads to fewer frustrated readers, and less work for you. (If a comment gets blocked, a legit user has a chance to try again.)
  • You won’t have to waste valuable time sifting through a spam queue any more, because there won’t be much there, if anything.

This plugin will add a client side generated checkbox to your comment form asking users to confirm that they are not a spammer. To combat the new ‘learning’ bots, this plugin adds dynamically named fields to the comment form so each post has a differently named field and value.

You can set the maximum amount of comments a user can have in the moderation queue to protect you from comment floods (provided you haven’t approved any of the spammers comments before) and prevent spambots from thinking they got links on your site by removing all links from comments that are waiting for moderation

7. Bad Behavior

Bad Behavior is a PHP-based solution for blocking link spam and the robots which deliver it. Thousands of sites large and small, like SourceForge, GNOME, the U.S. Department of Education, and many more, use Bad Behavior.

Bad Behavior complements other link spam solutions by acting as a gatekeeper, preventing spammers from ever delivering their junk, and in many cases, from ever reading your site in the first place. This keeps your site’s load down, makes your site logs cleaner, and can help prevent denial of service conditions caused by spammers.

Bad Behavior also transcends other link spam solutions by working in a completely different, unique way. Instead of merely looking at the content of potential spam, Bad Behavior analyzes the delivery method as well as the software the spammer is using. In this way, Bad Behavior can stop spam attacks even when nobody has ever seen the particular spam before.

Bad Behavior is designed to work alongside existing spam prevention services to increase their effectiveness and efficiency. Whenever possible, you should run it in combination with a more traditional spam prevention service.
