It is not a figment of my imagination: There were things going on besides multiple forms of outright plagiarism within several submissions. Because there are often multiple forms of plagiarism occurring in the same submission, once you catch it, it's pretty clear cut that it was deliberate. It is not only in writing but at actual conferences when she gives speeches.

The individual I mention is known to wear a custom "code t-shirt" of the program (aka "product") that she claims to be her original work, to conferences and meetups. The t-shirt along with the code itself has the /exact same specific variable names/ that I provided via email to a colleague years ago. She is also seen wearing this t-shirt in several media publications. She also publishes "research" based on this "work" in peer-reviewed journal articles. It really is quite disgusting.
