For those of us with 500+ & -2000 reputation, there are two review queues open: First Posts, and Late Answers. The LA I;m not worried about, but sometimes, in the FP queue, we have questions that show up with 0 votes, say something like 'asked 2 hours ago', etc, like a real post. If the question is good, and you upvote it/NAN, you pass the audit. If it is good and you DV/flag, you fail.
But with our new sandbox, new riddle questions that didn't go through the sandbox are DVed (sometimes), flagged, VTCed, and closed! This means tha if you DV and flag it in the queue, when actually the riddle was from before the sandbox, you will fail! So what'll happen now?
Disclaimer: I'm not 100% sure that flagging fails the audit. I think it does, though.
Disclaimer 2: This has not happened to me.... yet.
