Predatory journals, which mimic the names of reputable journals, do not provide peer review and often publish low-quality or nonsensical research without any editorial oversight. They charge high publication fees without offering value, and their articles are not indexed in databases like PubMed, resulting in minimal visibility and impact. While the lack of scrutiny allows for faster publication, it ultimately undermines the credibility of the research and should be avoided by authors seeking to be taken seriously in their fields.
