The email gave the students a form on which to admit or deny AI use on each assignment and warned that failure to respond would result in an F for the course and an unfavourable letter to the dean of students. It was sent on the deadline for dropping a class, and more than half of the class unenrolled. A student quoted by the newspaper said the main objection was that he had not said which assignments were flagged or how they were detected. After a weekend of attention on social media and a class discussion called by the department, it was announced that the allegations of cheating and AI use so far in the semester were dropped and that anyone could re-enrol. The professor said he would keep using his AI detection tool. No source describes what that detection method was, and how many of the accused had used AI is not known.","incidentDate":"2026-04-01","incidentKind":"single_event","incidentDatePrecision":"month","exposurePattern":"unknown","reportedDate":"2026-04-21","aiSystem":"No AI system is identified.
