Unfortunately it doesn’t seem to be the case, specifically with talk pages where the history of the discussion with the editor who deemed it a “hoax” was, but you can see some remnants of it here:

I wasn’t the one who made the edits to the page itself, but I was involved in collecting the links to prove it wasn’t a “hoax” and helping make the case to the editor who refused to believe it was true.
