"This article was written, and the favourable review inserted, by user Llywelyn2000, who has claimed on the Welsh Wikipedia to be the copyright owner in it. See the page there for the book cover image, , where he wrote ""Prynwyd hawlfraint y nofel gennyf"", which means that he bought the copyright, as Google Translate will confirm . 

 As such there is a serious conflict of interest in my opinion.
