https://dissem.in/p/80133892/nomenclature-for-factors-of-the-hla-system-2004 and https://dissem.in/p/70990242/rheumatic-heart-disease have merged dozens of links for over ten DOIs each. This results in interesting but ultimately unhelpful suggestions for OA links such as this PMC ID: https://en.wikipedia.org/w/index.php?title=User_talk:OAbot&diff=907224614&oldid=891940262
In that case the title was different by one word, while journal and authors were the same and the years were different. We could repeat the entire matching on OAbot side but this should really be fixed at https://github.com/dissemin/dissemin/issues/512 (and certainly will, sooner or later).
For now we can just ignore such papers. I found that anything with more than 2 DOI links is at risk.
