Downsides I could see:

 - These pages are linked to from
   and might have some small utility

 - Just blocking the /TitleIndex and /WordIndex won't keep Blue Coat
   from predictively scraping other URLs in that section.

   From a rough grep, 10% of the page hits on are 
   for action=raw or action=print. 

   (Since there is no UI for getting to action=raw or action=print
   I can find, we could also possibly just block those as well.)
