Suspected sockpuppets
In short, Dinomarek was a user blocked for making nonsense edits, including spamming article and talk pages with broad copy-pastes of scientific papers and admin comments, consistent with a non-native English speaker (self admitted to be Polish) trying to discount the evidence of feathers in non-avian dinosaurs, which has been the scientific consensus since 1996. One of their main areas of focus appears to be on scansoriopterygid dinosaurs like Scansoriopteryx, its possible synonym Epidendrosaurus, and the bat-winged Yi qi; Dinomarek edit-warred about the perforate acetabulum (a part of the pelvis) of Scansoriopteryx, constantly claiming that its anatomy is opposite what scientific sources describe (example edit here)

Two months after Dinomarek was blocked, Yipower123 (possibly named after Yi qi) posted copy-pasted rants on the talk pages of myself and PaleoNeolitic, two editors who have disagreed with Dinomarek. The rants seemingly downplay the fact that Epidendrosaurus is a dinosaur (a fringe hypothesis not accepted by the majority of paleontologists), while their only other edit rants about Epidendrosaurus' perforate acetabulum. It’s worth noting that User:PaleoNeolitic raised suspicions that they are Dinomarek.

Two months after that, POWERTYU (notice the similarity to Yipower123) posts the same exact rant on a random talk page. They also spam the talk pages of users who undo them (here and ); before their block, PaleoNeolitic and I often reverted him, only to be greeted with spam on our talk pages (compare the edit history of Halszkaraptor with those of my and PaleoNeolitic’s talk pages). It’s worth noting that POWERTYU’s “undo” messages have copy-pastes of the edit logs of the Polish interface, compare with the copy-paste of the “odpowiedz” from the edit reply tool here and Dinomarek’s confession that they are Polish.

Hydralisk 12345 (note the similarity to “Yipower123”)’s first edits are to request page rollback on Feathered dinosaur to an anti-feathered dinosaur edit made in 2021, which suggests they are not a new user. After their three requests (one of which to a bot) are declined, they add a similar, possibly copy-pasted and modified anti-feathered dinosaur edit here; Dinomarek’s edits are of a similar nature and also sound like professional sources poorly modified to sound like original thoughts.

After Hydralisk’s edit is reverted by User:SlvrHwk with the summary “this doesn't make sense …”, Hydroman 123 (the similarity to the previous editor is obvious) inexplicably copy-pastes the same edit summary to remove a passage discounting the presence of feathers in Kulindadromeus and Psittaccosaurus. While this is a complete 180 from previous edits, it should be known that Dinomarek’s edits often fluctuate from being pro-feathered dinosaur to anti-feathered dinosaur very quickly, sometimes regarding the same exact debate (as seen in the immediately preceding links), so it’s not out of character for Dinomarek to remove it. Additionally, Dinomarek seemed to be obsessed with the removed citation, as they have copy-pasted a rant about it on at least four different. talk pages.

I know some of these accounts are stale, but if possible can they be blocked on behavioral evidence? Atlantis536 (talk) 07:15, 21 July 2023 (UTC)
