Can you explain that again differently? I didn’t understand that captcha point. It feels important though.
From https://en.wikipedia.org/wiki/ReCAPTCHA:
> The original iteration of the service was a mass collaboration platform designed for the digitization of books, particularly those that were too illegible to be scanned by computers. The verification prompts utilized pairs of words from scanned pages, with one known word used as a control for verification, and the second used to crowdsource the reading of an uncertain word.
So I give you two words to transcribe to prove you are human. I know one of them and I want to know the other.
