Right, I guess it's time for you to upgrade the UI of your tool then, as when it's inactive it says "Anti-Robot Verification" and once the challenge is done it says "I'm not a robot", while in reality, none of those things are true, as you said yourself. You might also want to rebrand to use a different word than "Captcha" as you're not actually telling robots and humans apart, you're simply adding PoW to an action, nevermind if they are robots or humans. So instead of blaming users for misunderstanding your message, maybe try working on making your messaging a bit clearer so for the people who know what captcha is, don't get confused by your own definition of it.
