I am sure you are right.  To be honest, the last time I tried this I think I 
was running with the default robot_expire, but with RobotLimit 1000.  So 
even though RobotLimit was very high, it only took 1 visitor per day from 
the same IP to keep the counter counting and eventually reaching 1000.  Then 
once the 1000 limit had been reached the situation was quite bad as lockout 
lasted for a whole day.

Thanks for you help and patience with me on this one.
