What Are Predatory Journals?
Predatory journals are publications that exploit the open-access publishing model by charging article processing charges (APCs) while providing little or no legitimate peer review, editorial services, or quality control. They exist primarily to collect fees, not to advance scholarship.
For researchers in Hong Kong — where publication records are closely tied to funding evaluations such as the Research Assessment Exercise (RAE) and University Grants Committee (UGC) reviews — publishing in a predatory journal can seriously damage your career and credibility.
Key Warning Signs of a Predatory Journal
No single indicator definitively marks a journal as predatory, but a combination of the following red flags should raise serious concern:
1. Aggressive and Unsolicited Email Invitations
Legitimate journals rarely cold-email researchers with flattery-laden invitations to submit manuscripts or join editorial boards. If you receive an email praising your "outstanding work" and urging rapid submission, treat it with extreme caution. Check the sender's domain — predatory publishers often use free email services like Gmail rather than institutional addresses.
2. Implausibly Fast Peer Review
Genuine peer review takes time — typically several weeks to several months. If a journal promises decisions within 24–72 hours, this almost certainly means peer review is cursory or nonexistent.
3. Vague or Missing Scope Information
Many predatory journals claim to cover an implausibly broad range of disciplines. A journal titled International Journal of Science and Humanities that accepts everything from chemistry to cultural studies is a significant red flag.
4. Hidden or Unclear APCs
Predatory journals often do not disclose fees upfront. Researchers may only learn about charges after submitting — or even after acceptance — making it difficult to withdraw without potential embarrassment.
5. Fake or Misleading Indexing Claims
Claims of being "indexed in leading databases" should be verified independently. Check directly on Scopus, Web of Science, PubMed, or DOAJ to confirm whether the journal is genuinely listed.
6. No Verifiable Editorial Board
Search the names of listed editors online. Predatory journals frequently list scholars without their knowledge, or populate boards with fictitious individuals.
7. Poor Website Quality
Look for typos, broken links, plagiarised "About" text, stock photos presented as real editorial staff, and absence of a physical address or verifiable contact information.

What to Do If You Have Already Submitted
If you have submitted to a journal you now suspect is predatory, act quickly:
- Send a formal withdrawal email immediately, stating you are withdrawing consent to publish.
- Do not pay any invoice if you have not yet done so — payment may complicate the situation.
- Consult your institution's research integrity officer for guidance.
- If the article has already been published without your authorisation, document everything and seek advice on retraction procedures.
A Final Note for Early-Career Researchers
Early-career researchers and postgraduate students are disproportionately targeted by predatory publishers, often because of pressure to build publication records quickly. Remember: one article in a respected, peer-reviewed journal is worth far more than ten publications in predatory outlets. When in doubt, consult your supervisor or your institution's library research support team before submitting anywhere.
