I deliberately pick wrong answers in reCAPTCHA sometimes. I’ve found out that the audio version accepts basically any string slightly resembling the audio, so that’s the easiest way. (Images on the other hand punish you pretty hard at times – even if you solve it correctly!)

For images ones I have to turn off my brain. “Select all images that contain a crosswalk.”

What about unmarked crosswalks? Does it have to contain the crosswalk in whole or in part? That bit of white stripping is there just on the edge of this image, does that count? There’s a crosswalk in the background does that count? Etc etc.

The answer to all these questions is generally that you shouldn’t be asking. I can almost hear someone saying “You know what we mean.”
