You can override robots.txt behaviour using 'Set 
options'/'Spider'/'Spider' : 'Do not follow'

But ensure first that you can safely download sections 
protected by robots.txt - this is often large data, 
numerous cgi files and other potentially "dangerous" 
(bandwidth, disk usage) files. Use bandwidth limits if 
necessary (1 simultaneous connection, and bandwidth limit 
to 10KB/s)
