Their listings are fairly accurate-- if postmaster@ or abuse@ doesn't work for 
a domain, then listing them is perfectly correct, but the question is what 
that means.

It's probably better to use rfc-ignorant RBLs for scoring purposes, rather 
than as an absolute pass/fail test, even if you whitelist popular domains.

Internet domains are public (by definition): it's perfectly reasonable to 
expect there to exist a published point of contact available via WHOIS.

That said, I also do not care for the notion of blacklisting entire TLDs...
