At risk of being regarded as rude and unhelpful, I'd suggest
that such is not the list operator's job. They're merely
offering a list to MTA admins, not dictating that it be used
nor how. If the MTA admins want to punch holes in a list
used as a blacklist, perhaps by overlaying a different list
used as a whitelist, they can. If they want to maintain
such a list, intended to be used as a whitelist, they can -
and if they want to offer that list to others, they can.

In the meantime, any argument should be between the users
at each end of a mail connection, and their mail admins.

But this is not really an Exim topic, and might be better
carried on in news.admin.net-abuse.email.
