I'm currently posting this with TornTools enabled.
Arson crimes require monitoring and timing, and I just had a captcha trigger in mid-crime, booting me out and making me click on a grainy ass image to try to identify all squares with cars fast enough to get back into crimes and hit my fire with an extinguisher before first responders arrive and before the fire exceeded 80% damage.
Captchas really shouldn't trigger in the middle of a playing session when you are designing more and more mechanics to require active participation and timing.
