Or how about this?
 
Remember that <listname> is completely unable to control subscribers' and
researchers' behavior, and that no owner/editor of <listname> is responsible
for any final destination of a <listname> post. This is the same condition
as exists on other lists. If you believe that <listname> should be responsible
for the behavior of its subscribers or for researchers who look at our logs,
you must unsubscribe immediately. Such a demand is absolutely impossible
to fulfill and unfair to make. Send SIGNOFF <listname> to [log in to unmask]
or @HOST (Bitnet). By being a subscriber you accept that the listowner
and list editor, whether they are one, two, or more people, is/are absolutely
exempt from blame and responsibility for the actions of any subscriber(s)
or researcher(s), even if the list is moderated.
