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.
