I just failed an audit on this question: https://softwareengineering.stackexchange.com/review/first-posts/60664.
This was submitted as a first post from a new user, but that's wrong. I remember this post and it was mostly definitely not from a new user. I searched for it as a duplicate and couldn't find it, on either Programmers or SO.
My recollection is that the question was down-voted or deleted. It was not really a very good question, so maybe it really was deleted.
So I was intending to flag it as a duplicate by someone apparently cheating the system, registering a new user so they could ask the same question again. Instead, I got the "you failed an audit" rap over the knuckles.
Surely this is always a risk if you set real questions as audits that could easily have been seen by the reviewer? I know it doesn't 'really' matter, but somehow it doesn't seem the right thing to do.
Some helpful answers and comments prompt me to make one small suggestion. Since it appears that failing an audit may not be all that rare even for experienced reviewers, perhaps the language could be reworded slightly. Less of the "gotcha" and perhaps more of the "we all miss one occasionally but don't make a habit of it." Just a thought.
