I uploaded the robot.txt file to the server root, copied the WU_History files into their folder and check the results with hopeful anticipation, but this is what I observed
I tried:
User-agent: *
Disallow: /WU_History/
and then:
User-agent: *
Disallow: /WU_History/index.php
Neither stopped the onslaught.
