Yes, usually.  Or possibly the address was removed but LISTSERV
received some bounces for it after the removal.  (For instance a mail
server might generate a bounce after trying to deliver a message to a
given recipient for five days.  In this case LISTSERV will probably
continue to receive bounces for five days after the address has been
removed.)

In general, no.

You may wish to temporarily set your mailing list to

        Auto-Delete= Yes,Semi-Auto,...

(I assume your current setting is Yes,Full-Auto); LISTSERV will then
forward bounces from addresses not subscribed to the mailing list to
the listowner for inspection.  That should clarify what the bounces
related to the "ghost" addresses are.
