I can only talk about myself, and I haven't had to do this kind of essay since school roughly 20yrs ago. I remember pretty vividly that my ability to formulate good essays varied massively between days. (And it's the same now, though it's code instead of essays nowadays.) There are days on which I struggle being coherent and others on which things just flow out - sentences chain together into a fantastic essay. The proposed idea would absolutely fail people like me as cheating. Honestly, this whole debacle was obviously going to happen and anyone with half a brain predicted it when these services (the fraud detection ones) started to pop up.
