Best Anti-Spam Plugins for WordPress

If you have been around WordPress sites for a while, I’m sure that you know what spam is and how annoying it can be. But if you are new to this, spam is unwanted data that acts as a parasite or a leach and should be removed thoroughly.

Sick and tired of #spam? Use one of these anti-spam #plugins to get rid of it, for good, at least on your own site!

Blogs are a typical target for spam comments. Some people use bots to generate multiple comments at a time and then spam them on sites/blogs for backlinks. So if you are running a blog or you are simply starting a new site, you must take spam protection seriously if you don’t want your site’s overall quality to go down.

Getting rid of spam is a simple process that can be done with the help of WordPress plugins quite quickly. There is a lot of junk on the Internet and it doesn’t benefit anyone else besides the spammers themselves.

Spam comments can cause your WordPress site a few problems such as slowing down your site’s performance, eating your network’s bandwidth, and more. This will cause your loyal members to have a bad experience and will result in higher bounce rates, and traffic loss.

Obviously, you don’t want that to happen and thus, you need to get rid of spam comments as soon as possible. Thankfully, there are many WordPress plugins, both free and paid, that can help you get rid of spam comments with just a few clicks here and there.

So basically, there really is no need to spend time deleting spam comments one by one, as you can remove them quite easily with the following anti-spam plugins and save a lot of time and effort.

Akismet Anti-Spam


If you were to ask a renowned web developer to recommend an anti-spam WordPress plugin – the first thing to pop in their mind would be Akismet, as it is the most popular and most widely used anti-spam WordPress plugin.

Its user base features over 5 million installations and the plugin has received some nice reviews as well.

The plugin comes directly from WordPress’s developers – Automattic, which ensures the best compatibility support and regular updates, of course.

To use the plugin, you’ll have to sign up at to get an API key, which you can use to activate the plugin. You can get the key for free if you are going to use it for personal and noncommercial use (personal blogs). Keep in mind that you’ll be limited to 50,000 comment checks per month. However, if you need more, you can get one of the paid versions (Plus or Enterprise), for $5 and $50.

Akismet checks comments and contact form submissions on your site/blog against its global database of spam, and blocks all malicious content from being published.

The data is uploaded to Akismet’s cloud servers for their algorithms to evaluate the safety of the comments. The ones containing spam are directly transferred to the spam queue. The clean ones, on the other hand, are directly moderated and published on the site/blog.

In case Akismet can’t figure out if something is spam or not, it’ll move the comment to the moderation queue, where you can decide what to do with it.


  • Automatically checks all comments and filters out the ones that contain spam
  • Status history allows you to see which comments were detected and/or cleared by the plugin, and which were marked as spam or were unspammed by an admin or moderator
  • URLs in the comment body reveal hidden or misleading links
  • Moderators see the number of approved comments from all users
  • A discard feature blocks the worst spam, which saves disk space and speeds up your site’s performance

Antispam Bee

Antispam Bee

Antispam Bee is probably the best alternative to Akismet, as it has been growing quite rapidly lately.

This plugin is a quick fix for all those unwanted spam comments that you’ve been getting. The plugin keeps IP address trackbacks in case the spammers want to come back to spam more and it blocks them from doing so.

All users go through the validation process and are synchronized with the centralized server. On top of that, the notification system notifies you of any spam comments and it automatically clears spam folders.

Also, you can use this plugin to block or allow comments from different countries and/or delete spam comments after a set number of days.

The best thing is that the Antispam Bee plugin does all of this completely for free and all you need to do is find it in the WordPress database and activate it. Unlike Akismet, you don’t need to register to get an API key.
