I was being plagued by fake robo users and had to delete manually. This has stopped them right in their tracks! Thank you!

massicam83 ڊسمبر 3, 2019

Great plugin. It's easy to use and it works perfectly!

charliepodcasts نومبر 12, 2019

Locked me out of my WP log in immediately after installing. Fortunately host gives me back end way in. Deleted plug in, problem solved

makas آڪٽوبر 8, 2019

Free version does not work with woocommerce, you have to buy premium edition. So there is no way to even test it before paying for it. There should be a notice in the description about it. The description only say "Captcha Bank supports WooCommerce, BuddyPress & Contact Form 7." but no mentioning it's supported only by the premium edition. Just wasted my time trying it on a few websites.

sighttosoul آڪٽوبر 7, 2019

But have to pay for the premium version in order to have Captcha on my contact form or anything to do with Woocommerce, so not as helpful as I hoped.
