The journal Tumor Biology is retracting 107 research papers after discovering that the authors faked the peer review process. This isn’t the journal’s first rodeo. Late last year, 58 papers were retracted from seven different journals— 25 came from Tumor Biology for the same reason.

It’s possible to fake peer review because authors are often asked to suggest potential reviewers for their own papers. This is done because research subjects are often blindingly niche; a researcher working in a sub-sub-field may be more aware than the journal editor of who is best-placed to assess the work.

But some journals go further and request, or allow, authors to submit the contact details of these potential reviewers. If the editor isn’t aware of the potential for a scam, they then merrily send the requests for review out to fake e-mail addresses, often using the names of actual researchers. And at the other end of the fake e-mail address is someone who’s in on the game and happy to send in a friendly review.

Fake peer reviewers often “know what a review looks like and know enough to make it look plausible,” said Elizabeth Wager, editor of the journal Research Integrity & Peer Review. But they aren’t always good at faking less obvious quirks of academia: “When a lot of the fake peer reviews first came up, one of the reasons the editors spotted them was that the reviewers responded on time,” Wager told Ars. Reviewers almost always have to be chased, so “this was the red flag. And in a few cases, both the reviews would pop up within a few minutes of each other.”
