# psst, hey kid! wanna blackhole countries with the flick of a wrist?
CC=$1;[ -z $CC ]&&printf "Usage: $0 <country code>\nex:\n$0 cn #China\n"&&exit 1
[ "$USER" != "root" ]&&printf "root required.\n"&&exit 1
ZONE="http://www.ipdeny.com/ipblocks/data/countries/${CC}.zone"
curl -s $ZONE | xargs -I, ip route add blackhole , metric 999

That would work too, but there are some county codes (14) in the zone.tab that are not on the ipblocks website.
