So, yes, to exclude someone from future queries would require some change to the data in the DB or LDAP directory (most likely not full removal, but often the setting of some flag). But this must happen outside of LISTSERV. So far, most uses of this technique come from membership organizations (corporations, academic institutions, etc.) where receiving the "Important Emails" is considered something like a 'condition of employment' so the concept of unsubscribing simply does not apply. While there are no doubt some kinds of emails which must go to everyone, there are others which are less urgent/applicable, and for which a sub/unsub action of some kind should be available. How this gets implemented in actuality is certainly a challenge.
