CazoodleBot is a very stupid crawler which follows the Robots Exclusion Standard.
It identifies itself as:
CazoodleBot/Nutch-0.9-dev (CazoodleBot Crawler; http://www.cazoodle.com; firstname.lastname@example.org)
 Web site up, no information
www.cazoodle.com gives a page that says "Coming soon!".
 IP involvement
CazoodleBot appears to be operating from 220.127.116.11 (220-130-191-231.HINET-IP.hinet.net.) in Taipei, Taiwan.
It may be a good idea to disallow CazoodleBot in robots.txt or -j DROP 18.104.22.168 (or 22.214.171.124/24) like a hot potato.
