the domain away. i've set its NS to "localhost". i've put long

Instead of using localhost how about you set the NS record to '' and have an A record pointing to some of your dead IP space. That way the RBL client on the mail server will wait for a while attempting to connect to a dead machine. This will create a log jam at the inbound SMTP daemon, spinning off lots of processes, hopefully jacking up the load on the box and tweaking somebody's interested. Maybe even a tarpit type machine that can string the RBL client along long enough to cause enough delay/processes on the server to mean something. It is probably safe to assume if they are still using the domain after 8 years they probably don't have timeouts set for the RBL client lookups. Route the dead IP to a bogus LAN so you don't ARP yourself to death.
