I failed a review audit based on this question
I recommended it for closure (largely opinion based). But this is not what the audit expected.
Can anyone explain the rationale for this?
AFAIK, the review audits are evaluated autmatically by at least the following criteria:
But we all know that the highest scored questions on SO are not good questions.

Again, the only rational explanation is the judgement of the actions taken on the audit question failed to recognize the correct actions. It sometimes happens when a question has been upvoted and has no close votes. This is an example of community failing to close the questions which should have been closed. Don't blame yourself for failing - most of us probably would fail it too. It's closed already so just forget and move on :)
If failing this review gave you a review ban I am sure when a mod sees this topic they will remove it for you.
