I think you were referring to this part with "errors creeping in", such as the Usenet storage servers probably using cheap/old drives & controllers with bit-rot & bit-flips before it got to the TCP/IP stack.

Probably also using cheap/old network equipment too that would bit-flip between when the TCP/IP checksum was recalculated. And like you said, combined with the re-publishing of corrupted files if they didn't bother to par2 correct them first (ie., human errors creeping in :)
