Not if he posted via the Usenet!

USENET has limited post history maintenance.

Real INN servers have finite disk resources,
and so after a period of time, old messages
scroll out of existence. The server has what
are known as "high-water and low-water marks",
and that's how the client determines which
messages are no longer available for reading.

Google might well have the deepest history of any
INN server. Some of their dejanews archives go back
20-30 years. But the archive is not a complete set,
and it's not 100,000 groups times 30 years of content.

Commercial INN servers (used for movie distribution,
monthly charge for connections), those go back 10-12
years, and can be as hole-filled as Swiss Cheese,
due to DMCA takedown notices. Some USENET posters,
upload 1TB of movies per day, to battle against
the movie industry takedown notices that remove
1TB of movies a day :-) We're talking seriously large
flows of data, something that HomeOwnersHub could not
hold a candle to.
