Any mechanism for confirming an article genuinely came from the party named in it. Usenet's original design had none, since headers were trusted as written, which made forgery and sporgery straightforward. Later additions such as PGP-signed control messages, PGPMoose approvals, and Cancel-Lock covered narrow cases. Ordinary article headers remain unauthenticated, so a From line on its own proves nothing at all.
