In truth there's

    DNSBL operators MUST NOT list 127.0.0.1.  Therefore, a positive
    listing for 127.0.0.1 SHOULD indicate that the DNSBL has started
    listing the world and is non-functional. »

and again, in point 3.5:

«  A functioning DNSBL MUST NOT list 127.0.0.1.  There are a number of
    mail server implementations that do not cope with this well, and many
    will use a positive response for 127.0.0.1 as an indication that the
    DNSBL is shut down and listing the entire Internet.»

"Listing 127.0.0.1" is not the same as "returning 127.0.0.1".
