For what it's worth: during the years that I administered Hydra, I found
that many bots disregarded the robots.txt file that was in place there.
In practice, I found that I needed to periodically scan the access logs
for bots and forcefully block their requests in order to keep Hydra from
becoming overloaded with expensive queries from bots.

     Regards,
       Mark
