Friendly Captcha for WordPress

On first sight this CAPTCHA solution is what many people are looking for: Easy to implement and fully GDPR-compliant.

With the "Personal" plan there is a free plan available however I got an email from the friendly captcha team to upgrade my account. The smallest pricing option is 9 € a month. Sorry guys... for providing a simple piece of software 1.080 € over 10 years is ridiculous and I am out.

Good but...
