In my observations, I have come across a practice where some researchers include foreign authors, particularly from underdeveloped countries, as the last author in their papers. This is done in order to obtain waivers or discounts in Hindawi journals. I am curious to understand the strategies researchers employ to overcome financial constraints in open-access publishing.
However, I have concerns about the ethical implications of this practice. I would like to explore whether this approach could be considered unethical within the research community.
