Most of the time they use OCR, humans are unreliable and rarely used.

  That doesn't seem to match the sales pitch at antigate.com, deathbycaptcha, etc.

  no, at least antigate doesnt. When you hit recaptcha with known proxy urls (or generally hit it a few times per hour) the captchas get so bad that no OCR would be able to solve it, even humans struggle

    yup, exactly. i tried tesarract before (nothing too fancy), it didn't have problems solving it, but at some point it became really hard. I think part of it is how you crawl (phantomjs, for example, seem to hit captcha almost every time), but things like ip&proxy usage could make this trigger more often.

  Antigate can solve things that would give OCR fits, like animated letters and the like.
