Spam Destroyer

Kills spam dead in it's tracks. Be gone evil demon spam!

GravityKit

<p>This Gravity Forms add-on blocks spam using a non-obtrusive anti-spam measure and can email a spam report summary.</p>
<h3>Spam blocking for Gravity Forms</h3>
<p>To get started, all you need to do is activate the plugin!</p>
<h3>Is the Gravity Forms honeypot field not working for you? 🍯 🐝</h3>
<p>Zero Spam is better than the Gravity Forms anti-spam honeypot field. If you’re getting spammed, try this plugin.</p>
<h3>Use this plugin instead of reCaptcha</h3>
<p><strong>reCaptcha is user-hostile!</strong> Use this instead! Users don’t need to click stoplights, crosswalks, or bicycles when you use this plugin to stop spam.</p>
<h3>Enable or disable filtering per form</h3>
<p>If you only want the plugin for specific forms, that’s possible! The plugin adds a simple “Prevent spam using Gravity Forms Zero Spam” setting to each form (requires Gravity Forms 2.5 or newer).</p>
<h3>Spam report emails</h3>
<p>Spam summary report emails are disabled by default. Once enabled, a spam summary that includes the number of entries per-form will be sent via email.</p>
<p>Choose whether you want to be notified after the number of entries reaches a threshold (e.g. 10 spam entries) or after a certain number of days (e.g. every week). If there are no spam entries, no report will be sent.</p>
<p>Requires <a href="https://www.gravityforms.com/?partner_id=1210629&irgwc=1&utm_medium=affiliate&utm_campaign=1210629&utm_source=Katz%20Web%20Services%2C%20Inc." rel="nofollow ugc">Gravity Forms</a>.</p>

Gravity Forms Zero Spam

It helps way more than Gravity Forms' built in features, and it's nice to try invisible options before making users deal with Captcha quizzes. :)

Appreciate this plugin a lot!

Besides its simple approach, David Walsh’s “Zero Spam” technique, it works well.

Simple and effective

An amazingly simple yet successful strategy, this plugin captures pretty much all automated spam with little chance of false positives. No need to bother people with nasty CAPTCHAs, just install this plugin enjoy the ensuing peace.

Sends automated spam to the bit bucket

Enhance your Gravity Forms to include anti-spam measures originally based on the work of David Walsh's "Zero Spam" technique.
