Very good question. I see this in a lot of the papers I review. It seems a relatively 'safe' type of hacking in the sense that the hacker can always go "oops, didn't know that one, thank for the tip!" and then publish anyway (often without citing). https://twitter.com/SchildChristoph/status/1248936852561764352

This isn't only a problem with individual researchers, but also with research traditions. There are great examples in my field of that. Sub-disciplines suddenly discovering that people gesture, or do turn-taking, conveniently ignoring decades of literature on these topics.
