Zero Spam for WordPress

Has been my go-to anti-spam plugin for quite some time. I've used many of the techniques individually on many sites. Having them rolled up into a single plugin is just amazing!

All 1-star reviews that say it doesn't work, don't have it setup/integrated properly, which can take a little bit of effort. There is no magical anti-spam protection that instantly happens when you activate it. BUT, once you do implement a few of the techniques this plugin provides, spam becomes a thing of the past.  

Prior to v5.2.15, would have been an easy 5-star rating. Because of v5.2.15, I regrettably have to give it 1-star review. Plugin author: This is an ANTI-SPAM plugin, NOT a Ukraine support plugin. If you want to show your support for Ukraine, make a plugin for it. DON'T ruin a useful plugin by injecting unrelated political beliefs it into it. Blocking spam is blocking spam. Supporting Ukraine is supporting Ukraine. Mix them together and you just end up ruining both.

v5.2.15
    feat(ukraine): we’ll no longer provide protection for .ru, .su, and .by domains & will display a banner of support for the ukrainian people on those sites – united with ukraine

Personal Note to the Plugin Author:
It's your plugin, you can do what you want, but here's an important question: Is this plugin for YOU (the plugin author) to broadcast political beliefs, or for US (the plugin users) to block spam? Between those two, which one is more important? Pick one and go with it. If you pick personal political beliefs over plugin user functionality then it's only a matter of time until someone takes all of your hard work on this plugin, removes your political beliefs, releases it as a new plugin, and surpasses you in # of installs, making this plugin obsolete. You will be your own undoing. Would hate to see that happen to an otherwise WONDERFUL & AMAZING plugin!

Remove personal politics from this plugin, and my review will change to the 5-star review that it deserves.

Politics Ruin Yet Another Good Thing


I am using this plugin on all of my sites and it is really helpful in reducing spam. It has a very broad range of functionality and integrates well. This plugin also has good support. Great work


Very useful plugin


It's an obvois pay to use plugin with a direkt URL to the License Key website, which is basically prohibited by wordpress.org. It's even very intrusive with its payment demand. Since I have installed these type of plugins, I have more spam than before.


Pay to use

No spam, no scams, just seamless experiences with Zero Spam for WordPress - the shield your site deserves.

Most spam filters make your visitors do the work by solving captchas, clicking image grids, or proving they are human before they can leave a comment. Analytical Spam Filter takes a different approach. It analyzes how a submission behaves and blocks spam automatically, with no friction for legitimate visitors.
Key Features
<ul>
<li>No captchas</li>
<li>No API keys</li>
<li>No third-party services</li>
<li>Privacy-friendly design</li>
<li>Behavioral spam detection</li>
<li>IP reputation tracking</li>
<li>Content fingerprinting</li>
<li>Cache-compatible operation</li>
</ul>
Install it, activate it, and it starts working.
Spam is identified by observing behaviors that real visitors naturally exhibit. People take time to read before typing, interact with the page, and use a real browser. Bots often skip those signals. The plugin uses those differences to distinguish legitimate submissions from automated spam without interrupting the user experience.
The plugin uses multiple independent detection techniques on every submission. A bot that bypasses one check is likely to be caught by another. This layered approach improves effectiveness over time. Once a spammer’s IP address or message content has been identified, future attempts can be blocked more quickly. Visitors with a previously approved comment are never flagged, regardless of the spam history associated with their IP address.
No visitor data is sent to external spam services, and no account registration or API configuration is required.
All field names added by the plugin are randomized during installation and can be regenerated at any time. This helps prevent bots from targeting the plugin based on known source code signatures. The plugin is compatible with caching plugins when Cache Compatibility is enabled.
The plugin blocks spam submitted through the default WordPress comment form only. It is also automatically compatible with the Micro Contact Form plugin.
<h4>Blocking Methods</h4>
<ul>
<li>Timestamp Blocking — Records when the page loaded and when the form was submitted. Submissions that arrive too quickly to have genuinely read the page, or after the token has expired, are blocked.</li>
<li>Duration Blocking — Measures how long the visitor actively spent filling out the form. Bots fill forms almost instantly. Requires Cache Compatibility to be enabled.</li>
<li>IP Blocking — Remembers which IP addresses have been blocked before. Once an address reaches the configured threshold, future submissions are flagged without running the remaining checks. IP addresses with a previously approved comment are never flagged.</li>
<li>Content Blocking — Remembers the content of blocked spam. If the same message appears again from a different IP address, it is flagged immediately. Content that matches a previously approved comment is excluded from the spam history.</li>
<li>Honeypot — Adds a hidden field that legitimate visitors never see or interact with. Bots that fill every available field are caught. Submissions where the field is missing entirely are also flagged.</li>
<li>Automated Client Detection — Blocks submissions from automated tools that do not identify themselves as a real browser. Legitimate visitors send this information automatically.</li>
<li>Referer Check — Blocks submissions that did not originate from a page on your own site.</li>
<li>URL / Domain Blocking — Flags submissions containing more URLs or domain names than the configured limit. Spam comments frequently contain multiple links.</li>
<li>JavaScript Check — When Timestamp or Duration Blocking is active, the plugin can determine whether JavaScript ran when the form loaded. Bots that skip JavaScript are caught automatically.</li>
<li>Randomized Field Names — Hidden field names are randomized during installation and can be regenerated at any time from the settings page, so bots cannot target the plugin based on known field names.</li>
<li>Trackback Blocking — Optionally block all trackbacks, which are a common source of spam.</li>
<li>Pingback Blocking — Optionally block all pingbacks, which are a common source of spam.</li>
</ul>
<h4>General Options</h4>
<ul>
<li>Send email notifications for blocked spam, valid submissions, or all submissions</li>
<li>Configurable email rate limit to prevent inbox flooding during attacks</li>
<li>Add spam to the WordPress spam queue, or block and reject it immediately</li>
<li>Optionally show rejection reasons to the submitter</li>
<li>Enable Cache Compatibility for caching plugin support and duration blocking</li>
<li>Regenerate security keys at any time from the settings page</li>
</ul>

Analytical Spam Filter

Stop spam without making your visitors prove they're human. No captchas, no accounts, and no external services required.
