<p>I like to use Contact Form 7 on most of my WordPress sites. It’s a powerful form manager that suits all my needs. I don’t like to use external calls to protect the forms from spam submissions though (like reCaptcha or hCaptcha) and don’t want to present a manual captcha to a user (math or other puzzle). Since I couldn’t find a really basic honeypot script that works on most entries, I created one here. Hopefully it’s useful to someone else also.</p>
<h3>Setup</h3>
<ul>
<li>Install the plugin using the regular plugin setup routine or upload the entire apiosys-honeypot-cf7 folder to the /wp-content/plugins/ directory.</li>
<li>Activate the plugin through the “Plugins” menu in WordPress, you MUST have Contact Form 7 AND Flamingo installed and enabled.</li>
<li>Add the following shortcodes to your Contact Form 7 forms:</li>
</ul>
<p>[honeypot] – Adds the hidden honeypot field<br />
[timestamp] – Adds time-based validation</p>
<ul>
<li>Complete the rest of the options which you can find in Admin > Contact > Honeypot. A generally good working set of values is enabled by default there.</li>
</ul>
<h3>What tests are used?</h3>
<ul>
<li>A Honeypot Field</li>
<li>A Checkbox Trap</li>
<li>Time-Based Validation</li>
<li>Email domain Check</li>
<li>Basic Content Analysis</li>
</ul>
<h3>Does it really work?</h3>
<p>It has been tested on several high-traffic WP sites. I see a return of ~ 1 ‰ (i.e. 1 in a thousand) of spam going through. That usually corresponds to humans paid to fill forms or sophisticated bots. Please feel free to contribute to make it even better.

Apio systems – Honeypot for Contact Form 7

Basic Honeypot plugin for Contact Form 7 to drastically reduce spam on form submissions without user interaction.

WP-Biz (Ryan)

<p>The “honeypot” technique for SPAM protection is invisible to humans, and tricks robots into filling out an invisible form field. Then, if that invisible field has been filled, the form cannot be submitted. Easy, non-instrusive SPAM protection.</p>
<p>No settings to set, this honeypot is added to all Formidable forms on your site, unless the user is logged in. When SPAM is suspected, the form will not be submitted and the visitor will be alerted to this fact.</p>
<p>Tested to work with both <strong>Formidable</strong> (free) and <a href="http://www.wpbiz.co/go/forms" rel="nofollow ugc">Formidable Pro</a> (best bet for awesome form power!)</p>
<p><strong>A note to Formidable Pro users:</strong> You paid to receive extra features in the Formidable plugin. Me too, it’s well worth it. This Honeypot plugin, and Ryan (the developer) are not connected to Formidable in any way. Since this adds another very helpful feature to Formidable, I ask you to send a <a href="http://wpbiz.co/donate/" rel="nofollow ugc">donation at WPbiz.co</a> to say thanks and encourage future developemnt.</p>
