Scopus has discontinued over a dozen additional journals included in our "Invasion of the journal snatchers" analysis. A fast reaction time by bibliographic databases is crucial for defusing the business model of stealth journal transfers.

What is the most profitable industry in the world, this side of the law? Not oil, not IT, not pharma.

It's *scientific publishing*.

We call this the Drain of Scientific Publishing.

Paper: arxiv.org/abs/2511.04820

I wish ORCIDs were more widely used. You can add a secondary email address to your ORCID account, so even if you lose your institutional email, which is the norm rather than then exception, you can still use the same ORCID.
194: Author verification everythinghertz.com/194

We discuss whether preprint servers and journals should introduce author identity verification for submitting manuscripts. This would probably speed up the submission process, is this worth the potential downsides?

In today’s pay-to-publish model where every paper lands somewhere, rejection just means another publisher profits. That's why publishers are building multi-tier journal ecosystems.
"Acquiring the Karger journals will provide OUP with many more downstream transfer destinations, helping OUP to publish more of the articles that get rejected by their higher impact journals."

Depressing assessment of the commercial strategy guiding academic publishing.

36 cites to the same author? Retracted.
59 of them? Not retracted!

4 self-cites? Retracted.
21 self-cites? Not retracted!

70 unused cites to the same author? Retracted.
77 of them? Not retracted!

Plagiarism? Cites authors didn't add? 113 cites to the TPC chair in a 0.5-page paper? Not retracted!
Good news: ACM retracted some problematic papers.

Bad news: Only some, without apparent logic, as you can tell by following the links of my old blog post.

Doesn't look like they understand the concept of trust in an organizing/reviewing committee.
