Yep, about a decade ago an expert on a subject was talking about it. He corrected a page because the info presented with tons of sources all ended up taking their info from a single unreliable source. He had to edit things multiple times, making sure to follow guidelines, basically creating a new section that condensed his work on the subject to explain the controversy and so on... The page was edited back to its previous version every time because he didn't have enough local reputation and "older sources are more reliable"...
