Strange outcome of a “review audit”

There are sometimes audits when doing reviews on MSE, and I perfectly agree with that.

It's my understanding that usually, people who ask questions should show what they have tried to tackle the problem, so that MSE is not just a "do my homework for free" site. Questions that do not satisfy this minimum ought to be closed.

I have just come across this audit, that puzzles me. The question comes from here: Does $A^{-1}A=G$ imply that $AA^{-1}=G$?

Do I have to reevaluate my understanding of what is expected in questions?

To be clear: I understand that the question is not trivial and may be very interesting, but I think it's irrelevant to this.

Another funny one: getting a "STOP!" because I have written a comment to a high quality post. The review machine looks drunk. I agree with the comment of Lord_Farin below, yet it's strange to get such messages for no apparent reason.

• Bottom line: if your intention is good, ignore failed audits. – Lord_Farin Mar 29 '16 at 15:56
• What the others said. If I had the power to handpick questions used as review audits, this question would most certainly not make the cut. A good question masquerading as a bad question would trip many honest reviewers. – Jyrki Lahtonen Mar 31 '16 at 5:00
