Do I ask in
SSID [webmasterworld.com], in
Asia/Pacific [webmasterworld.com] or in
Yahoo [webmasterworld.com]?
IP: 183.79.218.various (appears to be legitimately Yahoo Japan, based in Osaka)
UA: Y!J-ASR/0.1 crawler (http://www.yahoo-help.jp/app/answers/detail/p/595/a_id/42716/)
I don't read Japanese and I strongly distrust the results of Google Translate; is that a list of possible UA elements in the middle of the page? It looks more like a list of VCR model numbers.
Preliminary visit requesting robots.txt followed by one interior page; longer visit yesterday, again beginning in robots.txt, followed by 30 pages over several hours. So no issues with their behavior; I'm just curious. To the best of my knowledge, IP and UA are both new to me, and I can't find a thread talking about them in detail.
