It is unethical to publish research that has not yet been published or communicated by the authors. The research work is that person’s work and it is their right to choose whether and when to put the paper online. What you can do is to cite it and share it, but only when the author has decided to publish it.
Publicly sharing unpublished research can be beneficial in some cases, but it requires a commitment to academic ethics to protect the rights of researchers and ensure the accuracy of the content.
Sharing unpublished research papers or publications on public platforms can pose ethical dilemmas, such as copyright issues. If a work has not been formally published by its author, they retain all rights to that content. Therefore, if it is shared without their consent, the rights of the person who conducted the research are violated. Another ethical dilemma that we would not be fulfilling could be the issue of integrity and scientific rigor. By sharing author's work, we would be bypassing copyright review processes that guarantee the validity and quality of research. Therefore, sharing something without this process could lead to errors. In conclusion, if we publish unpublished research papers on any platform, we should do so with caution or not at all.
