Anti-Spam

Josh Smith

The best anti-spam protection to block spam comments and spam in a contact form. The most trusted antispam solution for WordPress and WooCommerce.
Akismet checks your comments and contact form submissions against our global database of spam to prevent your site from publishing malicious content. You can review the comment spam it catches on your blog’s “Comments” admin screen.
Major features in Akismet include:
<ul>
<li>Automatically checks all comments and filters out the ones that look like spam.</li>
<li>Each comment has a status history, so you can easily see which comments were caught or cleared by Akismet and which were spammed or unspammed by a moderator.</li>
<li>URLs are shown in the comment body to reveal hidden or misleading links.</li>
<li>Moderators can see the number of approved comments for each user.</li>
<li>A discard feature that outright blocks the worst spam, saving you disk space and speeding up your site.</li>
</ul>
PS: You’ll be prompted to get an Akismet.com API key to use it, once activated. Keys are free for personal blogs; paid subscriptions are available for businesses and commercial sites.

Is Contact Form 7 spam destroying your mornings?
Every day, the same nightmare: dozens of fake submissions, worried you’ll miss real customers, and other plugins want $60/year just for basic protection.
This free plugin ends that nightmare today.
<h4>What Gets Protected (FREE)</h4>
✅ Contact Form 7 – Block bot spam automatically 
✅ WPForms Lite & Pro – Stop automated submissions 
✅ Jetpack Contact Forms – Filter bot spam instantly 
✅ Fluent Forms – Eliminate bot attacks 
✅ SureForms – Block bot spam submissions 
✅ WordPress Comments – Clean comment spam from badbots 
✅ Business sites included – No commercial fees ever
Works immediately after activation. No configuration. No learning curve. No monthly costs.
<h4>How It Works</h4>
3 Steps to Spam-Free Contact Forms:
<ol>
<li>Install – Search “Contact Form 7 spam” in your WordPress dashboard</li>
<li>Activate – One click to turn on protection</li>
<li>Relax – Your Contact Form 7 and WPForms and others are now protected from bots</li>
</ol>
The moment you activate, spam bots are automatically blocked on all your forms and comments. No settings to configure. No technical knowledge required. No ongoing maintenance.
Most users report 95-100% spam reduction within the first 24 hours.
Tomorrow morning, check your inbox. Instead of dozens of spam submissions, you’ll see only real customer inquiries. That’s the peace of mind this plugin delivers.
<h4>Why Contact Form 7 Needs This</h4>
Contact Form 7 is WordPress’s most popular form plugin with over 5 million active installations. It’s lightweight, flexible, and completely free.
But it doesn’t include spam protection.
Without protection, Contact Form 7 sites get hammered. Bot networks discover unprotected forms and flood them with submissions. Your inbox fills with junk. You waste time sorting real inquiries from spam. Worse, you risk missing legitimate customers buried in the noise.
This plugin fixes that problem. For free. Forever.
<h4>Free vs Pro: What You Get</h4>
FREE Version (Most Sites Need Only This): 
✅ Contact Form 7 bot spam blocked 
✅ WPForms automated spam stopped 
✅ Jetpack forms protected 
✅ Fluent Forms secured 
✅ SureForms protected 
✅ WordPress comment spam eliminated 
✅ Works on business/commercial sites 
✅ Spam statistics dashboard
Automated bots cause 95%+ of spam. The free version handles this completely.
PRO Version (For Advanced Needs): 
⚡ AI-powered human spam detection 
⚡ Gravity Forms integration 
⚡ WooCommerce registration protection 
⚡ Email quarantine for review 
⚡ Custom IP blocklists 
⚡ Allow/deny pattern rules 
⚡ Priority support
Most Contact Form 7 users never need Pro. But if you’re getting manually-typed spam or need enterprise features, Pro has you covered.
<h4>Why This Works Better Than CAPTCHA</h4>
CAPTCHA makes your visitors prove they’re human by solving puzzles. It’s annoying, hurts conversions, and still lets some spam through.
This plugin takes a smarter approach:
<ul>
<li>Invisible honeypot fields – Bots can’t resist filling hidden fields that humans never see</li>
<li>Timing analysis – Bots submit forms instantly; real people don’t</li>
<li>Behavioral fingerprinting – Bot patterns are detectable and consistent</li>
<li>No user friction – Your visitors never know the protection exists</li>
<li>Lightning fast – All processing happens locally on your server</li>
</ul>
Your Contact Form 7 stays fast. Your conversion rates stay high. Spam disappears.
It just works. Quietly. Effectively. Completely free.
<h4>Common Questions Answered</h4>
“Will this work with my existing Contact Form 7 setup?” 
Yes. It integrates automatically with all CF7 configurations, custom fields, and extensions. Nothing breaks. Spam just stops.
“I’m not technical. Can I install this?” 
If you can install a WordPress plugin, you can use this. There’s literally nothing to configure. Install, activate, done.
“What about sites that aren’t in English?” 
Works perfectly on all languages. The spam detection doesn’t depend on language – it detects bot behavior patterns.
“My site sells products. Do I have to pay?” 
No. Unlike some popular anti-spam solutions that charge business sites, this is free for commercial use. No exceptions. No hidden fees.
<h4>Ready to Stop Contact Form 7 Spam?</h4>
Installation takes 30 seconds:
<ol>
<li>In your WordPress dashboard, go to Plugins → Add New</li>
<li>Search for “Contact Form 7 spam”</li>
<li>Click Install, then Activate</li>
<li>Done – your forms are now protected</li>
</ol>
Check your email tomorrow. Enjoy the silence.
