Greetings from your predatory journal! What they are, why they are a problem, how to spot and avoid them

Predatory publishers, also known as counterfeit, deceptive, or fraudulent, are organisations that exploit the open-access scholarly model by charging hefty article processing charges (APCs), often without the scientific rigour and ethical processes offered by legitimate journals. Their rising prevalence is of concern to the scientific community, as the consequences of falling victim to them can negatively impact academic integrity and reputation, and render an author's work worthless and untrustworthy. Common characteristics include inappropriate marketing and misrepresentation of services by targeting individuals with solicitation emails, inadequate peer-review processes, lack of editorial services and transparency about APCs, and false claims about citation metrics and indexing that cannot be verified. Given the infiltration of predatory publishers, authors are advised to proceed with caution when receiving solicitation emails and if in doubt, to follow the Think, Check, Submit checklist.
