Any connection with the daumoa robot? There's one that looks like this:

Mozilla/5.0 (compatible; MSIE or Firefox mutant; not on Windows server; + http://tab.search.daum.net/aboutWebSearch.html) Daumoa/3.0

and another that looks like this

Mozilla/5.0 (compatible; MSIE or Firefox mutant;) Daum 4.1

which comes from a different IP with different behavior. There are at least two, possibly three different ones; I'm still trying to sort them out.

Korea's daum corp is huge, many divisions.
