I rolled my own version of Anubis for reasons*, and > 80% of all traffic is bots that fail the challenge, even when white listing legit crawlers.
* I wanted an elixir version so I could run it alongside my existing apps instead of having it sit as a proxy in front of them. This way my existing apps can validate if the caller is already whitelisted and if not redirect to the challenger https://sphinx.8by3.com which sends you back to a site if you pass eg. https://tuhat.net
