Unwelcome or unconsented acknowledgments is an unethical practice seldom addressed. It constitutes a form of authorship abuse perpetrated in the acknowledgments section of published research, where the victim is credited as having made a contribution to the paper, without having given their consent, and often without having seen a draft of the paper. The acknowledgment may be written in such a way as to imply endorsement of the study's data and conclusions. Through a real-life case, this paper explores the issue of unconsented acknowledgments and makes recommendations to prevent its occurrence, thereby promoting research integrity.
