CleanTalk: Best WordPress Anti-Spam Plugin in 2025

If you have a website or run a blog successfully online, you will understand how annoying SPAM messages can be. Receiving spam messages from different sources is not new to any webmaster; keeping spam away from a website is a constant battle most website owners have to fight daily, but it’s never easy.

A website owner must prevent malicious activities and make their website secure and safe, though it’s easier said than done. Spam compromises your website, can spoil your reputation with search engines, and lower your ranking in SERP. That is why you need reliable protection tools like CleanTalk to protect your website from spambots.

One of my blogs was bombarded with Spam virtually every hour; on some days, I received up to 300 spam messages with different links to a series of spammy websites. I tried different anti-spam solutions to keep the Spam to a minimum, but honestly, none did the job 100%. I get spam messages from comments, contact forms, and registration forms.

It was a frustrating experience until I came across a plugin with a cloud-based firewall called CLEANTALK that did the job perfectly. The plugin helps keep the Spam away from the blog until today, and the most amazing thing about this plugin is that it works perfectly without annoying captcha or Recaptcha.

From that day onward, any comments, contact messages, or registration we received on the blog were legit. No more SPAM from any source again, and I am here today to introduce the same plugin to you and how it will benefit your website and keep your website SPAM-free forever.

Before we dive into how to use this plugin, let me introduce the plugin to you properly.

What Is CleanTalk?

CleanTalk is a cloud-based service protection that prevents your websites from spam. It is a solution that prevents and filters spam to protect your website from all unwanted and potentially harmful ‘annoyance bots’ called SPAM. It provides spam protection that is invisible to visitors and eliminates the need for CAPTCHA, math, questions, and answers, where visitors must prove they are real people and not robots on your site.

It is an anti-spam cloud-based protection that works perfectly on all major CMS like WordPress, Joomla, CraftCMS and Drupal. It also works on languages, Libraries, Classes, and frameworks like PHP, Python, Perl5, Ruby, and lots more. But today, we will focus on how it works on WordPress.

CleanTalk plugin effectively filters all the comments on your website, contact forms, registrations, cart orders, and more for spam. It works perfectly on your WordPress website without inconveniencing visitors; it is reliable anti-spam protection that lets you focus on growing your websites without spam. The plugin protects your website, comment section, contact forms, user registrations, cart orders, and many more.

It’s very easy to set up and use, and it’s the cheapest anti-spam plugin in the market with a free seven-day trial. This plugin is simply Amazing!

The New CleanTalk Firewall

One of the unique features of CleanTalk is the active firewall that prevents spambots from getting into your website. Its firewall is a cutting-edge tool that protects your websites against spam attacks. It does not wait for the spam to hit your website before filtering it; rather, the firewall blocks traffic at the HTTP level. It filters the inbound traffic, which protects and reduces the load on your server. With the CleanTalk firewall, the spam bots never get to your website, not to talk of attacking your site.

The Spam Firewall creates an extra layer of protection for your website, making it hard for any bots to hit it. The CleanTalk firewall serves as the first line of defence, blocking most spambots before hitting your website. While CleanTalk Anti-Spam is the second line of defence, keeping spam bots from making comments in your posts, contact forms, cart orders, and registration forms.

If you create a blog or have blog posts on your website, this feature helps prevent spam bots from visiting your website and not talking or commenting on your website.

With the CleanTalk plugin installed on your WordPress website, you’re sure of safety because the technology behind the plugin has over 6 million spam IP addresses in its database, so when a visitor hits your website, their IP details are checked against CleanTalk’s database spam IPs; if a match is found. If the visitor is a spam bot, CleanTalk will block them, and the visitor will get a blank page.

How CleanTalk Firewall Works

• Protects spam bots from accessing your website

CleanTalk Spam firewall blocks most of the spam bots before they get to your website at all. It prevents SPAM bots from coming close to your site.

• Reduce the load on your web server

To post spam, many spambots load the page, which burdens the database and the server, and when a large number of spam attacks, it can significantly impact the website’s performance. CleanTalk prevents this from happening.

• Protection against HTTP/HTTPS DDoS attacks

The DDoS attack is a malicious attempt to overwhelm your server or its surrounding infrastructure with a flood of Internet traffic that your server’s request cannot handle. Installing the CleanTalk plugin protects your server against this type of malicious activity.

• Protects Your website against RPC-XML attacks

RPC-XML was developed to standardize communication between WordPress and different other systems; it enables WordPress to communicate effectively with other platforms. As good as this may sound, it introduces security vulnerabilities and can be the venue to attack your website.

RPC-XML sends authentication information such as username and password with every request; hackers could use it to try to access your site.

A brute force attack might allow them to insert content, delete code, or damage your database. CleanTalk firewall protects XML-RPC from sending any authentication information from your site and protects your website from various SQL injection attacks.

• Spam Logs

The CleanTalk spam firewall’s log allows you to monitor the service work and report all incidents.
