It's an interesting and unexpected use of the data, and an
interesting solution to the problem of trackback-type spam and
abuse.  I'd be curious to hear how much of the abuse the various
lists catch.  In principle our spam-based data probably won't
catch all of the abusers.  We find that the abuse spaces are
usually somewhat different between the different media: mail,
blog, etc. 

Also the same request goes for your application: please be sure
to *not* check the common whitehat domains like google, yahoo,
w3c.org, etc., as that could add many unnecessary DNS queries:


Sample common domains to exclude from checking are linked above.
