I'm working on making Anubis way less aggressive so that it only challenges the worst of the bad bots. I found a pattern that the bots can't fake client side and I've turned that into a sample rule that I've deployed to my website.

    anubis_policy_results{action="CHALLENGE",rule="bot/lies-browser-but-http-1.1"} 3891

This is coming soon to an Anubis near you!
