Predatory journals aggressively market themselves and promise quick publication for a fee without providing proper editorial or publishing services. Their main goal is financial gain rather than communicating science. They take advantage of researchers in developing countries and the focus on quantity over quality of publications. Features of predatory journals include lack of contact information, broad topics to attract articles, and claims of being leading publishers without following standard practices. The rise of these journals is fueled by academic performance indicators, focus on quantity, and lack of oversight in scholarly publishing. Researchers must carefully check for journals on blacklists and follow transparency of peer review processes to avoid being preyed upon by predatory journals.
