What about likely violations?

I tripped over this edit which appears to be a cut-n-paste from a PDF, and mostly likely a non-open-access journal article. I've detailed some of the issues at Talk:Fokker–Planck equation. Main points:

• All the hallmarks of PDF cut-n-paste from a PDF are present, including formula duplication, unexpected utf-8 characters, etc.
• A search-engine search for key phrases does not give any results (i.e. its not an obvious COPYVIO.)
• The text is well-written, meaningful and appears to be technically correct. (i.e. its not some LLM slop.)
• The text fails to integrate with the existing article, using subtly different notation, terminology etc. It also repeats many key equations and assertions that were already made in the article. (i.e. no care was taken to integrate with the article; its just a raw cut-n-paste dump of content.)
• Based on the content, I suspect it is from an article probably written by David Holcman, on the topic of the narrow escape problem. Given that the content is not available anywhere on-line, that its clearly a copy, its of high-quality, and that it fails to integrate with the existing article, I conclude it is from a proprietary journal.

So it smells like a COPYVIO to me, but I cannot conclusively demonstrate it. Except for noting this here, I don't know what else to do. 67.198.37.16 (talk) 22:22, 6 May 2025 (UTC)[reply]

Sounds like you should remove the copied content and request a {{revdel}}. Primefac (talk) 11:59, 11 May 2025 (UTC)[reply]

How am I supposed to document copying from a creative commons source?

The source material is:

Pasha Zusmanovich, "Mathematicians Going East," Journal of Humanistic Mathematics, Volume 14 Issue 1 (January 2024), pages 114-167. DOI: 10.5642/jhummath.EGCM7534. Pages 118-119.

I adapted this for Stefánia Szilárd and it got tagged as a copyvio because there's an ArXiv preprint with similar text. I'm planning to create more articles working from this paper. How can I best make clear to new page reviewers ahead of time that it's not a copyvio? Are there other steps I need to take when copying text from an external creative commons source?

I think Special:Diff/1290467938 should answer your question; we have a lot of templates for various types of copyright that will alert readers of the copyright status of the provenance of the content. Primefac (talk) 00:25, 15 May 2025 (UTC)[reply]
