No kidding.  Some of us have gotten so tired of spam from Korea, both
stuff relayed from the west and Korean-language spam promoting Korean
web sites, combined with the complete lack of response to all abuse
reports, that we've blocked all mail from Korean networks.

It extends beyond spam. We run a fairly high-volume website for a client
that has a members area. We have seen nothing but continuous DOS and password
scanning attempts against the site(on the order of several thousand per
second) from numerous points across Korean IP space to the point that
we've begun blackholing all of it as soon as these attacks begin(several a
day.)

Scary stuff.
