CAPTCHA was surely a logical move for different service providers to fight against spammers, it seems to be melting down. 'Realizing the potential for massive abuse from spammers with anti-CAPTCHA capabilities, who could use the clean IP reputation to carry out various attacks over Email and Web space, Microsoft attempted to increase the complexity of their CAPTCHA system.

As this attack shows, those efforts have failed,' says Websense security researcher Prasad. Could there be any better CAPTCHA? A better solution?"
