Does A.A. support this function?Do I have to pay for incorrectly solved CAPTCHAs?
No! You don't pay for incorrectly solved CAPTCHAs.
The software that you use must have the ?Report as incorrect? function implemented. This function will be responsible of telling our service if the CAPTCHA that we served was incorrectly decoded.

There isn't a final verdict about this yet, but it will probably be free or a low cost upgrade similar to Answer Swipe (http://answerswipe.com)
