My point is that expecting time-pressed students to ignore freely available answer sheets is like expecting a hungry horse to ignore a carrot dangling in front of them.

There is nothing wrong with removing their ability to cheat, but purposefully uploading answer sheets and then getting angry that students made use of them isn't. In fact, it's not just wrong: it's ethically wrong.

I think the "anger" is merited since the students (1) cheated when they were clearly told not to and (2) marked answers that were "obviously wrong" which implies that not even a modicum of effort was invested in demonstrating knowledge.

The "busy" argument is a poor one. We're all busy. Part of gaining an education is learning how to manage your time. As a professor myself, I know for a fact that most students manage their time poorly, yet many students will still pull the "busy" argument when it simply doesn't apply. Rather, just admit to procrastinating. Either way, the outcome is the same (poor performance).

To sum up my sentiments to cheaters... "Play stupid games, win stupid prizes."
