Super simple plugin to use and does great job. No need for an external API, which is a plus. If you need basic spam protection without the hassle, it does the job. In most of the cases it's enough.

All work great

Great

Does what is required.

Works great

By alfy40 on January 25, 2022

This works great including on the latest version of Wordpress as of this writing. I'm using it with Contact Form 7. In my opinion the person who says it isn't working is either logged in (and has the option to hide the captcha for logged in users), or didn't select "Contact Form 7" to enable it on contact form 7 in the settings (it isn't selected by default). I am happy with this plugin. It's obviously not high security, but will prevent 99% of automated bots/spam in contact forms. I made the effort of rating it and writing this comment because it doesn't deserve 3.7 stars only. Thank you!

It is not working for me.
