"The authors of retracted articles gain the most out of the continuous readership and citations of their articles. We should all remember that an author’s h-index score does not distinguish between positive and negative citations. Therefore, even if a retracted article is negatively cited, the citations counts are still calculated towards a higher h-index. In addition, the references appearing on retracted articles also gain since they are too counted towards total citations."
