In Scientific Publishing, Predatory publishing, also write-only publishing or deceptive publishing, is an exploitative academic publishing business model that involves charging publication fees to authors without checking articles for quality and legitimacy, and without providing editorial and publishing services that legitimate academic journals provide, whether open access or not.

  Complaints that are associated with predatory journals include, but are not limited to: 

• Accepting articles quickly with little or no peer review or quality control, including mediocre and fake papers.
• Interfere with the editorial process to ensure acceptance of low-quality articles.
• Notifying academics of article fees only after papers are accepted.
• Aggressively campaigning for academics to submit articles or serve on editorial boards.
• Listing academics as members of editorial boards without their permission.
• Appointing fake academics to editorial boards. Allow editors to publish repeatedly in the journals they command.
• Mimicking the name or web site style of more established journals.
• Making misleading claims about the publishing operation, such as a false location.
• Citing fake or non-existent impact factors.
• Boasting about being "indexed" by academic social networking sites (like ResearchGate) and standard identifiers (like ISSNs and DOIs) as if they were prestigious or reputable bibliographic databases.
