NaverRobot masquerading as GoogleBot

I don't like it

218.145.25.12 - - "GET /robots.txt HTTP/1.0" 404 204 "-" "GoogleBot"
218.145.25.12 - - "GET / HTTP/1.0" 200 8399 "-" "dloader(NaverRobot)/1.5"
Haven't seen this behavior before. Why bother masking as GoogleBot if you're not going to do it right?
i.e. Googlebot/2.1 (+http://www.googlebot.com/bot.html) rather than just "GoogleBot"

It's been mentioned a few times recently:

FWIW. Just to add to the list of "crimes", Naver is also cacheing.

Update and confirmation:

Visited yesterday - just this one file. Just after that they switched UA to "dloader(NaverRobot)/1.5" and GOT another 71 files.

Got a visit from an adress in the same range and from the same organisation as claus.

IP: 220.73.165.140

User Agent: GoogleBot

It just looked at my robots.txt and left.

Seems a lot like the (false) GoogleBot is just the "robots.txt" checker for NaverRobot(*) - it seems they always come in pairs. BOth seem to use HTTP/1.0 as well.

Yesterday though, GoogleBot visited again, but NaverRobot never followed.
