I just failed an audit by not voting to reopen this SO question.
But, IMHO, it's a poor fit for SO and should be closed. I wouldn't hesitate to close it if I stumbled upon it as "off topic" or maybe even "not constructive". At the very least it's debatable, so it shouldn't be a review audit - it's too close to definitively call.
Is there any checking done to ensure currently-open questions that are offered as audits should in fact be open?
