I threw together tarpit logic for usemod:

# == Configuration ====================================
use NetAddr::IP;
use vars qw( $TarpitDir $VandalFile );

$DataDir     = "/tmp/mywikidb"; # Main wiki directory
$TarpitDir   = "/tmp/tarpitdb"; # tarpit dir
$VandalFile  = "/Users/patsplat/Desktop/usemod10/vandals.txt";

open(SOURCE, "< $VandalFile")
     or die "Couldn't open $VandalFile for reading: $!\n";
my $remote_addr = new NetAddr::IP $ENV{"REMOTE_ADDR"};
while(<SOURCE>) {
     my $vandal_host = new NetAddr::IP $_;
     if ( $remote_addr->within( $vandal_host ) ) {
	$DataDir = $TarpitDir;
     }
}

Cheers,
