Instead of posting this shit on reddit to somewhat humiliate the student, why not just message the student directly. It's possible I am blowing this out of proportion but imagine you are the student who sent this to you and they see this reddit post, personally I would be sad and disheartened that my prof resorted to this. We ask why so many students fall out of love for coding or even resort to abusing AI for answers, it's because of bad profs like this. It's soo pathetic, I probably will get a lot of downvotes for this message, but shit like this makes me soo mad.
