CaptchaFox for WordPress


When activate a plugin, you could see a settings with "Configure the settings for the CaptchaFox widget. Don't have a site key? Click here to create an account". And it linked to a dead link "portal.captchafox.com" (not working URL).



This plugin has too simple settings, and no helpful document to make it works.



2 first 5 stars reviews seems was fake by their team which violates a rule of WordPress community.
