It seems like everyone has a spam story or two to tell. And we’re not talking about in a lifetime. No, spam is an everyday nuisance and something we live with.
The problem impacts every corner of the web. Sure, it litters social networks and enterprise applications. But even the smallest websites are bombarded with phony comments, form submissions, user registrations, and e-commerce orders. This hurts the user experience and makes life miserable for site owners.
The popularity of WordPress makes it a juicy target for spammers. As with other malicious actors, spam bots sniff for the content management system (CMS) and start wreaking havoc. Without protective measures, your site could see hundreds or thousands of illegitimate entries.
Thankfully, WordPress plugin developers have created several options for blocking spam. As such, we’ve put together a list of the top spam-fighters on the market. Each takes a different approach and protects specific areas of your website.
Tired of dealing with spam? Odds are, we have just what you need!

Cloudflare’s Turnstile is designed to detect and block unwanted bots. If the app is unsure, it will “challenge” the user to click a checkbox. Create a free API key, and this plugin will add Turnstile to multiple areas of your WordPress website.
It works with popular form plugins, the WordPress login screen, comment forms, and WooCommerce. You have full control over where and when Turnstile appears.
Spam bots can harvest any email address or phone number that is published on your website. Email Address Encoder deters this behavior by encoding them in decimal/hexadecimal formats. Wrap your email links or phone numbers in the plugin’s shortcode, and bots don’t stand a chance.
A premium version automatically protects all detected email addresses and phone numbers.
WordPress has a built-in comment system, but you don’t want to leave it unprotected. Antispam Bee is a free way to clean up your comments, with a suite of settings designed to detect and reject spammers. You can block comments from specific countries, languages, or based on the time of day.
There are also options to delete spam automatically and notify site administrators.
WP Armour protects the WordPress registration and comment systems via a honeypot. It’s a user-friendly solution, as there are no CAPTCHA challenges to get in the way.
The plugin also works with popular form plugins, including Contact Form 7, Gravity Forms, and Formidable Forms. The premium “Extended” version adds support for even more plugins, including WooCommerce.
SilentShield allows you to choose between multiple CAPTCHA formats (math, image, or invisible honeypot) to stop spammers in their tracks. It’s compatible with form plugins, WooCommerce, and the WordPress login/registration/comments systems.
It also respects user privacy and is GDPR compliant out of the box.
Here’s a plugin that uses multiple techniques to fight spam behind the scenes. Activate Maspik, and the plugin will employ a honeypot, IP verification (limited in the free version), and blacklist detection. You can also set custom limits and block specific words from being submitted.
An AI feature will attempt to recognize spam patterns, and you can connect to various APIs for advanced protection.
Akismet has been around for what seems like forever and is bundled with WordPress. It’s a truly set-and-forget tool for eliminating spam from your website. You’ll need an API key to use it (they’re free for personal use; other uses require a paid subscription).
From there, the plugin quietly detects suspicious content and keeps your comments and contact forms clean.
