[NFBCS] Automatic Captcha solving

[Joseph C. Lininger]

Hi Curtis,
I know you already know the answer to your rhetorical question, but I am 
going to answer it anyway for those who don't understand why using OCR 
to solve captchas isn't going to happen.

The entire point of a captcha is to prevent automated systems from 
interacting with a page. If OCR or any other automated technology could 
be used to solve the captcha, there would be no point in using one. If a 
blind person could use OCR to solve it, so could any other automated 
system incorporating OCR technology. The same thing goes for any other 
automated solution one might come up with for the solution of captchas. 
In fact, captchas are specifically designed to be hard to solve by 
automated means. For example, the ones that require you to enter a code 
you see on the screen have the code blurred, in funny fonts, or 
otherwise obscured in a way that makes it hard for automated systems to 
recognize the characters. Most captchas today do have an audio option 
that you can use as an alternative to the visual captcha. You might 
argue that this is harder than just using an automated solution, and 
you're right, it is. That's the point though; the captcha is designed to 
explicitly require human interaction in order to proceed.
