One thing's clear: if you send an abuse notification to NiceNIC, it ends up being really 'nice' for the criminals.

This reminded me of an idea for proxy filtering: filtering based on the domain registrar. Another practical use case for the WHOIS history database.

Is there an open and public list of the worst registrars?
