Predatory publishers aim to exploit the open-access model by publishing counterfeit journals and charging publication fees without providing proper editorial and publishing services. They often target inexperienced researchers. Jeffrey Beall, who coined the term "predatory open access publishing," warns that these publishers use deception to appear legitimate and entrap researchers into submitting work and paying fees. The number of predatory publishers has grown rapidly since 2011. Researchers should carefully vet journals and publishers to avoid predatory practices by checking for full contact details, legitimate editorial boards, transparent fee policies, and signs the operation may intend to deceive authors.
