By accident I discovered this issue. If you have 99% of the CAPTCHA words typed in it will allow the message to go through. For example, it gave the words of "gingham would" so I typed in "gingham woul". Even with the "d" missing it accepts it. I have not continued to see how many characters it will let you leave off, however, I figured I'd mention this.

I just did a bit of testing. The first line is the CAPTCHA and the second line is what I entered and it accepted it.

Hi Krackerjax,

From what I remember that's how ReCaptcha works. Unless you have an IP address that ReCaptcha has flagged then the first word is the test and the second is used to decipher OCR'd text.

reCAPTCHA improves the process of digitizing books by sending words that cannot be read by computers to the Web in the form of CAPTCHAs for humans to decipher. More specifically, each word that cannot be read correctly by OCR is placed on an image and used as a CAPTCHA. This is possible because most OCR programs alert you when a word cannot be read correctly.

But if a computer can't read such a CAPTCHA, how does the system know the correct answer to the puzzle? Here's how: Each new word that cannot be read correctly by OCR is given to a user in conjunction with another word for which the answer is already known. The user is then asked to read both words. If they solve the one for which the answer is known, the system assumes their answer is correct for the new one. The system then gives the new image to a number of other people to determine, with higher confidence, whether the original answer was correct.
