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. > You can't fake that, since it is (obviously) > not supported by the NNTP protocols. Either it is a sophisticated hack > - and that is not realistic - or it was the result of a server glitch. 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. -- vlaho.ninja/prog
