Are you sure that it was not being flagged as a robot? I'm pretty sure 
that the "Yahoo" entry in the default robots.cfg will catch "YahooSeeker" 
as well. Take a look at your interchange.structure file with debug 
enabled, and you can see the regex created for the RobotUA directive, and 
Yahoo isn't anchored so should match YahooSeeker too.

(In this case that's good, but in other cases you may find a RobotUA 
setting matches too loosely, such as "Google" matching "GoogleToolbar" or
