CAPTCHA 4WP – Antispam CAPTCHA solution for WordPress

The plugin authors removed CF7 support for the plugin with no prior warning, so all websites that were using it for their CF7 forms broke (I had in the range of 20 websites where the form validation had been silently broken this way), so they would display a broken "[anr_nocaptcha g-recaptcha-response]" shortcode. I rarely take my time to write a review for anything, but this definitely deserved it. You should warn users so that they choose to update or not; not simply make this change and let all existing CF7 forms break. Shame on you.

The plugin authors let all their sites break


For the past week, my site has been inundated with fake account registrations. Since adding this plugin yesterday there haven't been any new ones. I'm hopeful that it won't cause any problems for students signing up for my courses.


Yay no fake registrations today!


5 stars, no notes - MU/multisite support greatly appreciated


Perfect for me and MU support
