Best WordPress Anti Spam Plugins

1. Akismet


Download Link

This is the default anti spam WordPress plugin that you get when you install WordPress on your server. It was one of the first anti-spam plugins developed for WordPress and that too by the very same company that develops WordPress i.e. Automattic.

Akismet checks each and every submitted comment for spam links and later you can check to make sure it has flagged no legitimate comment. But this plugin is efficient enough to check and flag spam comments.

2. Antispam Bee

Antispam Bee is another plugin for WordPress that was appreciated by Matt Mullenweg at WordCamp Europe 2014. This plugin checks for some special factors for deciding if the comment is spam or not. You can set the preferences of this plugin to trust approved commenters on your WordPress blog.

This plugin also checks for IP addresses, Gravatar, etc. to make sure that no spam comment reaches you. It can keep a counter of the spam comments and display the stats related to spam which is a nice feature.

3. Anti-spam


Download Link

This WordPress spam blocker comes in two versions – one free and one that costs 15$. The free version is more of a fire and forgets a thing, as you don’t have to do any setup – you simply install the plugin, and it will do everything for you. The paid WordPress spam filter, however, has some more options for you, such as letting you add words for the spam filter and putting a max word limit on the comment length.

At a price of $15 the pro version makes sense, but that does not mean that the free version of the plugin is not functional at all. In fact, it is one of the most effective anti-spam plugins for WordPress.
