I am also using blackholes.us to block IP's that are from China.  The
problem I have, is that I continue to get e-mail which is in some
foreign language which I can't read.  When I run it through Spamcop, it
always comes up as from chinanet.  Not sure how I can stop this.  I
figured maybe if I start looking at the charsets, I can start blocking
some of this spam.
