Someone told me about an ingenious way that spammers were cracking "captchas" -- the distorted graphic words that a human being has to key into a box before Yahoo and Hotmail and similar services will give her a free email account. The idea is to require a human being and so prevent spammers from automatically generating millions of free email accounts.
The ingenious crack is to offer a free porn site which requires that you key in the solution to a captcha -- which has been inlined from Yahoo or Hotmail -- before you can gain access. Free porn sites attract lots of users around the clock, and the spammers were able to generate captcha solutions fast enough to create as many throw-away email accounts as they wanted.
Now, chances are that they didn't need to do this, since optical character recognition has been shown to be readily tweakable to decode captchas without human intervention -- that which a computer can generate, a computer can often solve.
My cow-orker Seth Schoen points out that human-generated captchas are much harder to solve: say, picking out a photo of an animal, at a funny angle, in a cage, and challenging attackers to correctly identify it. People can do so readily, machines probably can't.
Except, of course, that getting people to pick out pix of animals at funny angles doesn't scale. Unless, of course, you offered them free porn to do so ("Want free porn? Identify the animal in this cage!").
Which suggests a curious future, where commodity pornography, in great quantities, is used to incent human actors to generate and solve Turing tests like captchas in similarily great quantities.

A leaked Comcast memo discloses that the company’s consumer data caps have nothing to do with network congestion, contrary to its public claims. The internet service provider has often complained (such as when lobbying against net neutrality) that it must impose limits on service to prevent network congestion. The argument suggests that these measures are […]
