WP Rocket - WordPress Caching Plugin

It's 02:30.

You've been slaving away for days to get that first new blog post finished because you know it's going to help your visitors. One last check ... finally you hit publish.

You lie in bed satisfied and content, sleep a short night and wake up early. You flip open your laptop again and see responses (3).


Three new comments on my blog post! Nice. I'm curious to see what they have to say.

You hit the reply button only to discover that...

3 Russians with dubious email addresses offered viagra to your visitors in English with links to a website... Disappointed, you remove the three comments. Only to have to remove another two a day later.

This is where an anti-spam plugin comes in.

WP Rocket - WordPress Caching Plugin

Spam comments are one of the most irritating things to manage as a WordPress blog owner. Fortunately, there are several plugins on the market to filter and automatically remove these spam comments. In this blog post, I walk through the top 5 anti-spam plugin on the market:

  • Akismet
  • Antispam Bee
  • WordPress Zero Spam
  • WP-SpamShield
  • Cleantalk

What is an anti-spam plugin?

Malicious computer programs scan the Internet for places to post their information. These spam bots come out on the input fields of your articles and post text with links to their websites. The goal is to generate backlinks and websites clicks to their websites through the posted external links. Many times these are viagra, porn or other shady sites that you don't want among your comments.

It is tedious to manually delete every comment, and you cannot automatically allow your normal visitor's comments.

An anti-spam plugin ensures that your website blocks spam or even preemptively removes spam so that it does not enter the system again. Some of the plugins mentioned provide up to a full 100% reduction in spam.

1. Akismet

Akismet is a free WordPress plugin that allows you to block spam responses on your WordPress website. The plugin is installed with the initial WordPress installation by default.

The plugin originated in 2005 and captures approximately 7.5 million spam responses in one hour. That's about 9 times the population of Amsterdam in a single hour.

At the time of writing, Akismet has already blocked over 406 billion spam responses.

The beauty of Akismet is that when a new comment is posted on your blog, the comment goes to the cloud server first. There, a smart algorithm checks the comment and determines if the comment is spam or not.

Is the comment deemed clean and safe? Then it will be posted directly to the blog. Is it spam? Then the plugin puts the comment in the spam folder so you can decide what to do with it.


Akismet is wildly popular among WordPress users. The plugin is completely free for non-commercial WordPress websites. Which does generate some criticisms within the community.

If you choose to monetize your Web site you pay $5 per month. For larger companies, that amount comes to $50 per month.

Advantages and disadvantages of Akismet

  • Free for non-commercial use
  • Most popular anti-spam plugin
  • User-friendly
  • Paid for commercial use
  • Does not 100% capture all spam

1. WP-SpamShield

WP-SpamShield is another great WordPress antispam plugin. WP-SpamShield is immensely useful when you have huge problems with bot-generated spam, but you don't want to bother your visitors with a reCaptcha because users often find them annoying.

How WP-SpamShield works.

The plugin has two layers of spam protection that work together to block both bot and human spam:

  1. The JavaScript/Cookies Anti-Spam layer
  2. The Algorithmic anti-spam layer

The first spam layer is a dynamic combination of JavaScript and cookies to weed out those among the spambots. This provides a 100% prevention on spambots. Even if bot authors find a way to break it the second layer jumps in to block the spam.

Another nice feature of WP-SpamShield is the automatic protection for:

Contact Form 7 forms, Gravity Forms, Ninja Forms, JetPack Contact Forms; BuddyPress, bbPress and WooCommerce registration forms; Mailchimp signup forms; Virtually all other WordPress forms and registration forms.
