I agree, I'm not against cheating but high risk high reward. If you're dumb enough to include the lecturer in the very group chat you cheat in then you deserve to fail. The class was stupid to even think they could cheat as a whole class, its like robbing a liquor store with 80 accomplices. What you do is you find a small group of individuals you trust and you cheat together secretly and given how small that group is likely to be you're all forced to learn something.
