Human labour is thousands of times slower and thousands of times more expensive (even at $2.00 per 1000) than automated solving. The fact that spammers have been forced to use such inefficient solution techniques is proof of the captcha technique's efficacy.
Consider if these captcha's were not in place. By the above logic, there would be thousands of times more spam on sites like Google and Facebook.
- d0ne 15y agoWhile I agree that human labor is thousands of times slower and thousands of times more expensive than an all computational solution that is not the point most of the time for automated systems. In the case of messages and wall post on Google or Facebook, once a CAPTCHA is solved you get to send N messages before the next one is popped up. Without the CAPTCHA you could only go so fast anyway due to general rate limits so the impact on spam, for either service, is minimal. In the case of account creation in general the limit for automated systems is more heavily dependent on diversified proxy access more than anything else. Additionally, you can only effectively manage so many accounts at one time depending on your needs and CAPTCHA do not add more than a few % time delay to the overall account creation process.
