That would explain the incredibly large number of open proxies in 218/8.

Drew, I don't think you're being spammed by Koreans...at least not 
directly by the ones delivering the spam to you.  You're more likely just 
being spammed via open proxies that happen to be Korean.

It's your network...do what your customers will let you get away with.
How many Korean customers might you have that will be pissed when they 
find they can't exchange email with family and friends in Korea?  There's 
one sure way to find out.
