I always do the same when seeing a reCAPTCHA or other captcha from Google: Type the correct word properly, and a slightly off word for the other word, which seems plausible to naive OCR, but still is wrong.<p>From the ideological side, as long as Google profits from the work of users due to their monopoly, but doesn’t provide it as open dataset under a noncommercial license, I don’t wish to support reCAPTCHA.
