From the developer
GravityKit's own description of Gravity Forms Zero Spam, lightly tidied.
This Gravity Forms add-on blocks spam using a non-obtrusive anti-spam measure and can email a spam report summary.
Spam blocking for Gravity Forms
To get started, all you need to do is activate the plugin!
Is the Gravity Forms honeypot field not working for you? 🍯 🐝
Zero Spam is better than the Gravity Forms anti-spam honeypot field. If you’re getting spammed, try this plugin.
Use this plugin instead of reCaptcha
reCaptcha is user-hostile! Use this instead! Users don’t need to click stoplights, crosswalks, or bicycles when you use this plugin to stop spam.
Enable or disable filtering per form
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).
Works with Shield Security
If the Shield Security plugin is active, its silentCAPTCHA bot detection can be used as an additional spam signal — enabled globally or per form. You can also control the order in which the plugin’s spam checks run.
Spam report emails
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.
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.
Requires Gravity Forms.
