Great high-level overview. One of the challenges about learning about bot detection is that it's adversarial, and revealing info about your techniques can help the attackers evade you.

I do work on a bot detection product, and I've seen some group chats where crackers are sharing notes about how they're evading detection tools. The more unnerving part is that the public groups are less serious, and there are certainly better private groups aiming at anything with a good financial reward.
