Reporting someone for academic dishonesty is a deathblow to any kind of application to higher ed. This was an undergrad psych class I think? Anyone there trying to get into the PhD programs is in for a world of trouble now, that's a competitive place.
It's not that I think cheating is good, I just wonder if these students peers in this class/other schools who had better outcomes did things the right way, or maybe they just didn't have a professor who enjoys this so much that he will spend weeks writing R code to fully catch everything. That seems like an arbitrary way to have a dream end, I dunno.
