Here is a Register article describing a site being blacklisted by SPEWS.org
and how they are dealing with it:

The site in question was blacklisted for using an ISP that has been known
for hosting spammers in the past. SPEWS.org does not provide contact
information nor are their operations audited by anyone.
The problem with SPEWS.org specifically and other similar initiatives, is
that they do not provide contact information and there is no way to gauge
whether their internal operations are run properly. This is a problem with
all anti-spam tools and is something that should be addressed in the BCP
area. Additionally, mail administrators should be cautious when selecting
or relying on a specific tool (this also goes into BCPs). Within the
consent framework, these are SOURCE TRACKING COMPONENTs which should be
selected carefully.
