Can a Scopus-indexed journal still be predatory?
Indexing is the strongest single signal a researcher can check — but it is a status a journal holds today, not a character certificate it keeps forever. Understanding that difference is what keeps you safe.
It is one of the most common questions we are asked, and the honest answer unsettles people: yes, a journal can carry a real Scopus record and still behave badly, and a journal that was genuinely indexed when a colleague published in it may not be indexed now. This is not a reason to distrust indexing — it remains the single most useful check you can run, and it is central to our complete guide to identifying a predatory or cloned journal and to our full Scopus publication guide. It is a reason to understand what indexing actually certifies, and, crucially, when.
The short answer
Inclusion in a selective database like Scopus or the Web of Science Master Journal List is a strong positive signal, because these indexes apply published criteria and review titles before accepting them. But it is a probabilistic safeguard, not an absolute one, for two reasons. First, no vetting process is perfect, and a journal can meet the bar at evaluation and drift afterwards. Second — and this is the point most authors miss — indexing is continuously re-evaluated, and journals are removed. So "is it indexed?" is really two questions: was it ever indexed, and is it indexed today. Only the second one protects you.
How a weak journal gets indexed at all
Getting into a major index is genuinely difficult, but the system is not immune to gaming. A journal may present well at the point of evaluation — a plausible board, a reasonable early output, correct formalities — and only later shift toward high-volume, low-scrutiny publishing once the indexed status is secured and can be advertised. Others exploit the lag between misconduct and detection: the databases are large, and the interval between a journal's standards slipping and the index noticing can run to months or longer. None of this makes indexing worthless; it makes indexing a status that has to be checked fresh, not assumed from a badge or a colleague's memory.
Why Scopus discontinues journals
The reassuring half of the story is that the indexes actively police themselves. Scopus re-evaluates titles against its quality criteria and discontinues those that fall short — for reasons such as publication concerns, editorial-standard failures or metrics that signal manipulation — and it publishes a list of discontinued titles. Web of Science similarly re-assesses and can remove journals from its Master Journal List. This ongoing housekeeping is exactly why the index is trustworthy; it is also exactly why a one-time check is not enough. A journal on the discontinued list may still advertise that it is "Scopus indexed," because it once was — which is precisely the kind of stale claim you must verify rather than accept.
How to check current status
The check takes two minutes and settles the matter. Open the Scopus sources page directly and search for the journal by title or ISSN; confirm that it is present and that its status is active, not discontinued. Then cross-check the freely downloadable Scopus source list, which includes the discontinued-titles information, so you can see whether a journal was removed and roughly when. For Web of Science, search the Master Journal List the same way. Do all of this by navigating to the databases yourself, not through a link the journal supplied — a stale or fabricated "indexed in Scopus" badge is worth nothing; the live record is worth everything.
What a delisting means for your paper
If a journal is discontinued after your article was published, the usual position is that work already indexed generally remains in the database, but the journal stops being indexed for new content from the discontinuation point — so citation and coverage of anything you publish there afterwards is affected, and the journal's standing in evaluations may fall. If you discover that a journal you are considering has been discontinued, treat it as a clear signal to look elsewhere. If you have already published in one that was later delisted, do not panic — confirm the facts, keep your records straight, and see our guide on what to do if you have already published in a predatory journal. The exact consequences vary, so where it matters for a degree or a promotion, confirm the current position with your institution.
How I read an indexing claim
When I evaluate a journal's indexing, I never take the claim on the journal's own site at face value, and I never rely on the fact that it was indexed when I last looked. I open Scopus and the Web of Science Master Journal List myself, confirm the title is present and active on the day, and glance at the discontinued list if anything about the journal feels rushed or too accommodating. It takes a couple of minutes and it has saved colleagues from submitting to titles that were quietly removed months earlier. Indexing is the best signal we have — I trust it precisely because the indexes are willing to remove journals — but I trust the current record, never the badge and never my memory.
