What is in the logs. In particular, the entire 'bounce' log from 11/1
thru 11/24.

Do you mean admin_notify_mchanges is No, bounce_notify_owner_on_removal
is No or something else. When cron/disabled removes a member, it always
tries to notify the member. There's no setting for that.

Was cron/disabled running between 11/15 and 11/24?

Were changes made to the list's bounce settings after 11/1. In
particular, the number of notices (bounce_you_are_disabled_warnings) is
set in the user's bounce info when deliverry is first disabled and
subsequent changes to the list setting won't affect the number of
notices for that user.

Also what's in the subscribe log on 11/24. Where the 'unrelated'
unsubscribes all done at the time cron/disabled ran (default 09:00)?
