Was also curious about this step. I assume they're not going to reveal the nitty gritty details for fear of botters coding around it, but I am curious as to how you can "make them use more CPU" while crawling a website

Serve the suspected bots a page with Javascript that computes a proof of work, submits it, and gets the real page in return.
