Predatory publishing is a term for low-quality or scam publications. Berger and Cirasella describe these publications as, "primarily fee-collecting operations—they exist for that purpose and only incidentally publish articles, generally without rigorous peer review, despite claims to the contrary. Of course, low-quality publishing is not new. There have long been opportunistic publishers (e.g., vanity presses and sellers of public domain content) and deceptive publishing practices (e.g., yellow journalism and advertisements formatted to look like articles)."
