Captcha Spam Blocker


Full disclosure: I am the developer. I originally built this plugin for my own projects because I needed a simple and effective way to stop spam. One year after publishing it, I'm leaving this review to confirm it's still running flawlessly on all my sites. It has completely eliminated spam on my forms. It's a "set it and forget it" solution that just works.


Developer's Review: Still My Go-To Plugin After 1 Year

Enhance your site’s security with dynamic CAPTCHA, blocking spam and bot access on forms. GDPR-compliant.
