You're probably right. But the fact remains that captchas aren't good enough. They can be partially automated; blackhats can use captcha solving farms which will be at least as accurate as the average human (probably more accurate, I imagine).
A better solution might employ heuristics similar to DDoS mitigation techniques. I really don't know, but there is a need for something better here.
