So... If PoW (proof-of-work) schemes like Anubis ultimately don't' work in practise, because Bots/Crawlers are increasingly using headless browsers, are able to solve captures, proofs, etc;
What options do we have realistically to filter out or block unwanted traffic?
What clever schemes can we come up that don't rely on centralised serices like Cloudflare?

Personally I do not have an issue with bots as long as they behave and are not straight up malicious, so I rely on a combination of rate limiting, a fine-tuned OWASP CRS ruleset and an aggressive Fail2ban enforcement (hit 2 triggers and you get a 24 hour ban, 2 bans and you get banned for 30 days).
My sites also make extensive use of static elements and caching.
