Yes, the linked study does not substantiate any of the percentage claims made in the article but instead apears to be only related to the article by way of being about trolls. Since the link to the study is in a place where I would expect the link to the study that actually backs the article to be, I think either the author inserted the wrong link by mistake or, which I believe to be more likely since I couldn’t find a study that could have been the source of the article in the mentioned journal from that year, the entire article is AI generated and at least partialy made up. The article does not contain the word ‘reddit’ nor does it contain pictures so even of the experts interviewed, none mention reddit.
