Comments full of spam despite reCAPTCHA

[karibuTW]

Hello, I'm having a long lasting issue with spam on the comments sections as you can see here: https://freedif.org/community-forum-software-how-to-install-vanilla-message-board

the reCAPTCHA is implemented, but it cannot block the spammy comments. Any idea what is the issue and what could be done to improve it?

Also later I need to see how to improve the design of the comments (all packed at the moment)

My guess is that you are not processing captcha in the form. Please provide the full comments.yaml configuration file.
