See http://mail-abuse.org/dul/faq.htm#b_17 .

If listing are only the result of ISP requests, "take me off" requests
should also be honored without questions, but that is not the case :-)

Moreover, in at least one occasion the DUL folks told me that they
needed an actual spam sample to show in case the ISP complains for
the listing.

See http://mail-abuse.org/dul/adding.htm

I sometimes also ping the involved IP and its neighbors, and do it
again at a different time. If the set of IPs that answer change
with time, they are likely to be dialups.
