I've seen websites put up some draconian measures to try and get a grip on the scraping. So much for the sub-second loading experience when you have Cloudflare, Google, Anubis, and all these other captcha services trying to see if you're a human. It's made the web browsing experience so much worse.

Some of the proposals to address this include charging bots for access to web resources, but they will also have repercussions for regular users. I don't see how you solve this cleanly.
