TL:DR cloudflare made a new recaptcha which does some complex math and other stuff on your browser, which done once has no noticable effect but if someone were to scrape websites at an absurd speed it slows everything down significantly.
this is not only cool because you don't have to manually solve the captcha, but also because it allows for low-speed scraping to be feasible, with tools like flaresolverr
That's actually kinda cool. Punish the scrapers, but allow regular people to not waste time.
Meanwhile, Google is having you find the zebra crossing for the 400th time....

Oh, so it's Hashcash; cool to see that idea getting real use.
