Re: CAPTCHA image validation in web form

I don't know if TicketMaster uses CAPTCHA but as you know they are HIGH volume, public, etc., and even have a timer on the users response; no timely response, the tickets go back to the "available" status.   It really works as I've used it a number of times.

I visited their site, and it struck me that it's a very good case for 
CAPTCHA.  High volume public site, where users wouldn't want to be 
forced to register & authenticate on one hand, but on the other hand 
wouldn't want automated bots gobbling up all the seats for events; 
putting the average event patron at a disadvantage.

It also struck me that they use a high degree of distortion in their 
image and audio files.  I imagine they've had problems with bots.
