block china CIDR please!

for too many days i have been dealing with china as spammer as the get some info of our users so block this ip's have been annoying i have set up a persiste file with this guys but i have just found a web page with CIDR of china so i uploaded this on pf

pfctl -tdammed-hosts -Tadd ==myscrypt==

i use simple perl to get rid of all of the useless information as the file format it is:

#chinese net blocks CIDR
#http://www.okean.com/chinacidr.txt

1.0.1.0/24  China
1.0.2.0/23  China
1.0.8.0/21  China
1.0.32.0/19  China

...

so with the scrypt i eliminate all but 1.0.1.0/24 this goes to screen so i just used $(scrypt) to populate pf table

here is the web:
http://okean.com/asianspamblocks.html

here is the scrypt:
dont blame me am not a programmer }:)

#!/usr/sbin/perl

use strict;

use warnings;

open(myFH, $ARGV[0]);

foreach my $line (<myFH>){

 chomp$(line);

 my @val = split(' ', $line);

 print "$val[0]\n";

}

close(myFH);

of course no secury added to the scrypt as it is for my personal and for this situation but it works i have populated 2638 blocks for the pf table
