I don’t think you have a usecase for Anubis.

Anubis is mainly aimed against bad AI scrappers and some ddos mitigation if you have a heavy service.

You are getting hit exactly the same, anubis doesn’t put up a block list or anything. And most bots are not AI scrappers they are just proving. So the hit on your server is the same.

What you want is to properly set up fail2ban or, even better, crowdsec. That would actually block and ban bots that try to prove your server.
