I take strong issue with the CAPTCHAs.. You're essentially training Googles' image recognition engine for free.

  No, you're not. A captcha already knows the correct answers. Otherwise, it wouldn't know if your selections are correct. Besides, Google doesn't need help in picking out pictures of motorcycles or buses or bridges.

    It doesn’t know the answers are correct. I intentionally give it the wrong answers. Sometimes it realizes my answers don’t Match what is most common. So It doesn’t give me hard questions then. And doesn’t give me more than one prompt.

      That may be what makes it correct, but that's known in advance. My intent was to disabuse the notion that captchas are how Google trains for image recognition.

    The original reCAPTCHA, with two words: It knew the answer to one of the words and didn't know the other. At one point some users were inserting purposefully wrong answers or slurs into the unknown word to mess with the data collection. I expect the idea is the same with images, if there are 4 buses I expect 2 it knows are correct and used as a sanity test, 1 it's pretty sure it's correct (from majority of users selecting it), and 1 has some heuristics that might be a bus but it is currently testing to see whether users believe is or not. Similarly with the 5 not a bus images.
