See presentation by Luis von Ahn at http://video.google.com/videoplay?docid=-8246463980976635143

He talks about how spammers use porn sites to correctly input captchas back in July of 2006.

He also talks about a lot of other stuff which is pretty damn mind-blowing.

Folks that haven't watched this talk... you should. It really got me thinking in new ways. There's a reason why von Ahn won a MacArthur ("Genius") Grant for his Human Computation work.
