Anyway, I don't see anything in the article about what the academic office said when he turned all those reports in. I'm really curious, these kinds of situations tend to make national news when some prof brings a large number of students up on academic honor code violations. (ex: https://www.military.com/daily-news/2021/08/20/least-100-nav...)

I'm firmly of the opinion that the negatives of group study out weight the positives and generally should be banned in college. Banging your head against a problem for hours at a time assures you understand all the wrong ways of getting the right answer. This means you have a far more detailed understanding, and there is always formal academic study/the prof/etc and the possibility of asking about difficulties in class.

And finally, group chat is small potato's, I'm fairly certain there is a fair bit of 3rd parties basically doing assignments/taking tests these days for students. Primary because I was "mentoring" a student in a subject and found myself in a situation that I had to extract myself from because it crossed a line of mine.
