Hi, we have spam issues over a certain URL because it allows direct POST-Requests. The system has the ability to create subscribe forms. All these forms post their data to this URL: "/index.php/lists/XYZ/subscribe". The issue with that is, that bots easily mass-post email addresses to that URL and spam mails get saved to the database. The url "/index.php/lists/XYZ/subscribe" needs some type of spam protection like Google ReCaptcha or at least a honeypot. Please fix.
