Research in the Humanities and Social Sciences often faces complex ethical and methodological challenges. This article focuses on exploring questionable practices in this field through a rigorous methodology combining real case analysis, anonymous testimonies, and triangulation with public documents and case studies. This approach has allowed distinguishing genuine researchers from impostors and uncovering often concealed aspects of academic research, thereby providing a deeper understanding of the mechanisms and motivations behind fraudulent research practices. These findings underscore the importance of upholding scientific integrity, researcher credibility, and public trust in academic research. They also highlight pathways to address opportunistic practices and scientific fraud, which persist as challenges in Humanities and Social Sciences research. Solutions involve promoting a culture of integrity and accountability through comprehensive measures such as researcher education and awareness, regulation by independent and transparent ethics committees, transparency in publishing research findings, and fostering appreciation for ethical research.
