Solving and creating captchas with free porn: You know those distorted alphanumeric codes you have to decipher and type in on some sites to get access? They’re apparently called “captchas” and they’re meant to make sure you’re a real person, not a script. Well, here’s a flat-out brilliant way that spammers have been getting around them.
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.
