Bot captcha trap

I was thinking about a system where the player could click in someone and use an option like "Check player as a bot" in the report menu. In the screen of this player a captcha of 4 random digits or something will appear for him, he have 1 minute to digit the numbers on the screen, if he fails he can be throw to Mordion Gaol or get absolute bind where he can leave if he digit again the 4 random digits. In some way this could notify a GM and ban the person for using a third party program if the person fails in the captcha.
However, if this system will be used with malicious intent or baseless the person could face harsh punishment like the misuse of Report RMT.

That sounds like a great way for people to be harassed tbh even if it's reportable.

It sounds like a way to push thousands of afk players into gaol where the GMs would then need to deal with a bloated queue of players.
Also it's not like captchas can't be botted. There's easier ways to detect botting players.
