Isn’t fail2ban a possibility too? I created a filter for chatgpt and some others, and it feels like its working. My radicale server is my only free acessable service but it comes with a small webgui and so the bots showed up. I have no clue if the bot gets a fraction of your site each time it shows up, but seemingly the ban happens within 300ms when I remember correct. So it wouldn’t be that much of information…

When setting the retry to 1 it will ban at the first sight.
