This plugin adds a captcha to the registration process for new users to solve. It displays a simple calculation that the users has to enter in an input box. The question is retrieved via web sockets. Initially a honeypot calculation before the web socket calculation is downloaded will be presented.
This is probably not a good captcha for frequently visited websites. Consider using other captcha solutions like
nodebb-plugin-spam-be-gone. The math captcha might be more user friendly but provides less security against spam bots.
nodebb-plugin-prometheus plugin is installed and activated, this plugin will deliver additional metrics.
