I could also talk a lot like this how my students tried to cheat, and how I detected it. 20 years ago. I had to write special programs to detect written cheats. The online cheating during the written exam was easy to detect, the offline not so. But having written this program helped a lot, and I told nobody the details. In the end the cheaters were the minority. But if you allow it to spread, 90% will start cheating. The broken windows theory. PS: And I still talk a lot to my professor colleagues, who are still teaching at university. They told me that COVID was a total cheating desaster. Everyone cheated, everyone. It was impossible to do proper exams at the end of the course. They are all extremely frustated.
