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; email@example.com)
 Web site up, no information
www.cazoodle.com gives a page that says "Coming soon!".
 IP involvement
CazoodleBot appears to be operating from 18.104.22.168 (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 22.214.171.124 (or 126.96.36.199/24) like a hot potato.
