I have altered the  Subject:  to reflect the discussion. This is something
which someone (including myself) should have done several exchanges ago. I'm
also crossposting to  news.admin.net-abuse.usenet  since some administrators
of usenet servers hang out there and perhaps they can offer more insight.

Such an unusual glitch cannot happen independently on several newsservers so
it can only have happened on one and then propagated. If it propagated then
it should still be visible on other newsservers too since there's no
automatic mechanism to fix this nor would news admins have any reason to
assume there was an error to fix manually unless they happened to be reading
the discussion.

I assume "that" means that the  Newsgroups:  field in the header shows one
set of groups G but some server shows the message when you ask for messages
of a group P not contained in G. Yes , this would be hard to fake. The
From:  line is trivial to fake since severs will only check for correct
syntax.
