i guess there must be a DNSBL for that somewhere?

btw, the registrar for these is usually enom.com.

It is in alpha.  I would be keen to hear how it does for you.

Separately, I'm building some technology that acts essentially as a next-generation DNSBL: when queried, in addition to returning a response from a local lookup table, the server does some independent research as well: it looks for the whois record, determines the registrar, and and looks up the reputation of that registrar. All of this, and more, contributes to the reputation score, and shows up in the response.
