Stalke writes "Spammers are now usings a new technique to circumvent the 'captchas,' the distorted text in graphics, that users must input to receive the free email account. The spammers have cracked the system by displaying the 'captchas' on free porn sites in real time. Since there are always a large number of people signing up for free porn, they do the work of decripting the 'captchas' which is then replayed back into the spammers program to create a new email account. Who thought that porn could be a hacking technique!" Sure sounds plausible, though the link here says only "someone told me."
