Though the semi-automated systems using humans can break CAPTCHAs, there are still scenarios where using it makes sense. For example, to prevent DoS attacks, a CAPTCHA might be employed to route visitors from one part of the site to another. Even if humans are involved in this loop, the delay introduced in solving the CAPTCHA can slow down the attack.

However, I will stand by my opinion that the majority of CAPTCHA implementations, no matter how sophisticated, are generally ineffective at preventing what they were implemented to prevent.
