New Web Robot NaverBot very bad manners
A new Web Robot/Spider Out There Name NeverBoT, Version 1.0 from NHN Corp. / +82-2-3011-1954 / nhnbot AT naver.com
Have you check your web log in last few days? If yes, then you may notice a new Spider having footprint of "Mozilla/4.0 (compatible; NaverBot/1.0; " with a URL pointed to help.never.com and there is not a single English Word to read.
Never.Com is one of big search engine in Korea. This web spider/bot run by: NHN Corporation. Though they claim that this new Robot Maintain robot.txt file, I am not convinced.
For last few week, I keep an eye on this bot and found it normally ignore robot.txt file.
