From Wikipedia's CAPTCHA article
Spammers pay about $0.80 to $1.20 for each 1,000 solved CAPTCHAs to companies employing human solvers in Bangladesh, China, India, and many other developing nations.[23] Other sources cite a cost as low as $0.50 for each 1,000 solved.[24]
Another approach involves copying the CAPTCHA images and using them as CAPTCHAs for a high-traffic site owned by the attacker. With enough traffic, the attacker can get a solution to the CAPTCHA puzzle in time to relay it back to the target site.[25] In October 2007, a piece of malware appeared in the wild which enticed users to solve CAPTCHAs in order to see progressively further into a series of striptease images.[26][27] A more recent view is that this is unlikely to work due to unavailability of high-traffic sites and competition by similar sites.[28]
