Gravity Forms Zero Spam


This Gravity Forms add-on blocks spam using a non-obtrusive anti-spam measure. There are no settings or configuration needed: all you need to do is activate the plugin!

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.

Requires Gravity Forms.

Brought to you by GravityView. We create essential Gravity Forms Add-Ons.


Is this plugin PHP 7 compatible?


Does this plugin work in combination with other CAPTCHAs or spam blocker plugins?

Yep, you can use this plugin in combination with all other spam-blocking plugins:

  • Gravity Forms’ Google reCaptcha feature
  • WPBruiser
  • Akismet
  • Gravity Forms’ honeypot fields
  • GravityCaptcha
  • СleanTalk
  • WP Armor
  • fail2ban

Zero Spam will not interfere with the operation of those plugins.

What version of Gravity Forms does this work with?

This works with all Gravity Forms releases after v2.3 (released June 2017). The plugin also blocks bots in the latest Gravity Forms 2.5!

Will this block spam comments or registrations on my site?

No. For that, we recommend Ben Marshall‘s WordPress Zero Spam plugin.

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. 🙂

So far this is working great. I would welcome a premium version that gave you logged blocked messages for 7 days.

We looked to this solution because Akismet was marking too many false positives. This plugin performed miserably when we first tried it several months ago. Legit messages marked as spam, easily ID'd spam marked as legit. After being told recent versions were better we deployed it on 5 sites with relatively few incoming messages, and it it got it 99% right on 4 of the sites but flagged a significant amount of legit messages (20%) as spam on the other. All are running the same version (1.07 I believe). UPDATE: This past week we conducted an experiment by running it on a heavily messaged website - but one that uses the same platform and theme as the others. It performed miserably, flagging 50% of all legit messages as spam, especially those with a file attachment. Unfortunately, whatever mechanisms this plugin uses are not reliable for form spam detection. Back to the drawing board.

I can't believe I have not given this a review before. This has worked perfectly on scores of my client sites. Hugely valuable. Thank you for making this unobtrusive too.
