ReCaptcha is reliable

ReCaptcha has been working reliably for months

Works perfectly
by martink52·5 months ago

After fighting with bots creating accounts I gave this plugin a try and it worked as promised. A great plugin and conform with our privacy protection rules and laws.

Genius and perfect!!

This one is epic!!! I have been looking for 2 years now for a solution without recaptcha, stable, simple, lightweight, well-done, and actually working. Here it is, finally! Thank you so much!!

Absolutely Essential for Gravity Forms & Forminator Users
by Christian Saborio·8 months ago

This anti-spam plugin has completely eliminated spam across all our sites using Gravity Forms and Forminator. It’s fast, highly configurable, and works flawlessly without affecting performance. Setup is simple, and once it’s running, you don’t have to think about it again. Zero spam, no false positives—just solid, reliable protection. Highly recommended.

Absolutely Brilliant
by waradi42·9 months ago

This is a really fantastic plugin. One of the most useful things for me has been its ability to quickly identify usernames which have been compromised. I can then just set up a new user account, transfer all the posts and delete the compromised account. It also doesn’t bombard you with made-up attacks as some “security” plugins do.
