What the author says it does

The Anti-Spam plugin is trusted by over 200,000 websites and powered by a global spam detection network. CleanTalk “eats” spam before it reaches your website. By using cloud-based, API-driven analysis and shared spam intelligence, it provides more advanced protection than local, standalone plugins that don’t use a cloud API — helping catch spam they may miss.

🛡️ Anti-Spam Protection for your entire WordPress site

  • Contact forms — block spam submitted through Contact Form 7, WPForms, Elementor Forms, Gravity Forms, Fluent Forms, Formidable Forms, and many others.
  • WordPress comments — automatically detect and block spam comments.
  • WooCommerce — stop fake orders, spam registrations, and spam reviews.
  • User registrations — prevent spam accounts and automated registrations.
  • Subscriptions and bookings — filter unwanted and automated submissions.

✨ More Than Just Anti-Spam

  • 🛡️ Spam FireWall — block known spam bots before they reach your forms.
  • ✉️ Real-Time Email validation — detects fake, disposable, and suspicious email addresses.
  • 📋 Anti-Spam Log — shows every checked request, so you can see what was accepted or blocked and review possible false positives.
  • 🔒 Contact Data Protection — protects published email addresses and phone numbers from being harvested by bots.

Questions the author answers

Does CleanTalk stop contact form spam?

Yes, CleanTalk stops spam in contact forms, registration forms, comments, and other forms on your website. It uses a combination of algorithms and a cloud-based database to identify and block spam submissions in real-time.

Does CleanTalk protect WooCommerce from fake orders and spam registrations?

Yes, CleanTalk protects WooCommerce from fake orders and spam registrations. It checks all incoming orders and registrations against its anti-spam database and algorithms to ensure that only legitimate users can place orders or register on your site.

Which WordPress forms does CleanTalk protect?

CleanTalk protects all WordPress forms, including but not limited to:

* Comments

* Registration forms

* Contact forms

* Sign-up forms

* Search forms

* Subscription forms

Why are they spamming me?

Spammers want to get backlinks from your site to improve their site’s PageRank or redirect your visitors to malicious sites.This level of spam can damage your reputation with readers and commentators if you fail to tackle it. It is not uncommon for some WordPress websites to receive hundreds or even thousands of comments every week.

Is the anti-spam protection safe for mobile visitors?

Yes, it is. The plugin doesn’t block mobile visitors as well as desktop website visitors. It uses several independent anti-spam tests to decrease the number of false outcomes and to have as low false-positive rate as possible. Multiple anti-spam tests help to avoid false/positive blocks for real website visitors even if one of the tests failed.

How can I test the anti-spam protection?

Please use the email [email protected] for comments, contacts or signups to see how the anti-spam protection works. Also, you can see the logs for the last 7 days in the Dashboard or look at the folder “Spam” for banned comments.

Where this page's numbers come from

Read from the WordPress.org plugin API on , when WordPress 7.1.4 was the current release. WordPress.org rounds active installs into buckets. These are the directory's figures, not my verdict, and I haven't tested this plugin.
