This is horrifying but not surprising. We've always known "#plagiarism #detection" #software was crap, but schools keep using it anyway. "#AI detection" software is almost guaranteed to be even worse. I have no idea what to do about this, but I hope the student can get some kind of redress.
@ElemWiz I'm really, really glad I did most of my schooling before that was a thing. My dissertation work happened about the time Turnitin et al. were getting big, but if anyone ever ran that through plagiarism detection software, I didn't know about it. Students and professors both have reason to be paranoid these days, and that's not good for anybody. Except the companies making bank on proprietary black-box crap, I guess. 😕
