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!

Do you not want to use ReCAPTCHA because it’s user-hostile? Use this instead! There are no stoplights or crosswalks here.

Originally based on David Walsh’s «Zero Spam» technique. Requires Gravity Forms.


Is this plugin PHP7 compatible?


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 has performed miserably. Legit messages marked as spam, easily ID'd spam marked as legit. The fact that a legit, manually entered inquiry was marked as Spam on day 1 is deeply concerning based on how this plugin works. It should be impossible for a human to enter data into a hidden form field but that seems to be what happened. While it's a tough call to say this is worse than Akismet, it's certainly not better.

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.
