Anti-spam, Spam protection, ReCaptcha for all forms and GDPR-compliant


Blocked hundreds of spam WooCommerce orders, and the plugin continues to be actively monitored and improved. I'm sure it will continue to get even better. Great work.


Excellent


The developer is really motivated to get this plugin going. Nice guy.



And the plugin helps catching spam without violating GDPR. Great for german or EU-sites.



Thanks a lot for this plugin.


Works like a charm and great developer-support
