How to spot a dodgy journal? Possible signs of unfair practices:

• Rapid peer review, lack of or inadequate peer review.
• Inaccurate information on impact factor, misleading metrics (Global Impact Factor, IndexCopernicus), inaccurate information on journal indexing in databases.
• Reaching to authors with unsolicited emails regarding publication of articles or invitations to editorial boards (academic spam).
• Inaccurate or missing information on publication fees.
• General journal names, names similar to reputable journals, interchangeable abbreviation of a journal or an extension of a well-established name.
• Low percentage of rejected articles.
• Unclear identification of the publisher and editor; it is impossible or difficult to contact the publisher; use of generic and free emails.
• Questionable composition of the editorial board.
• The published articles are of low quality without scientific merit.
