Found that this previously was not obeying robots.txt. I don't know if it is now or not but here is an IP that took forever to track down. Finally pinned it back on e-SocietyRobot (through translated au and jp server logs of other companies...its amazing what google will index... :))
This accounted for 30k+ hits last month...waste of bandwidth? Does anybody know if this is useful? I don't sell in Japan btw.
