What exactly constitutes fraud? The captcha interface (http://www.captcha.net/ http://www.captcha.net/) has a clickable tagline "stop spam. read books." that takes you to an explanation of what it is and how it works. Are we saying that fraud is not going out of your way to carefully explain exactly what you're doing as you're doing it? Saying that Captchas are in any way misleading or fraudulent calls into question "free" software paid for by ads, any app that has a ToS contract, pretty much every financial agreement on the planet, most repair shops, and just about anywhere else that you agree to something without 100% ELI5 in your face explanation before you pull the trigger.
