Similar to Close votes review audits
Not a duplicate of What are review tests (audits) and how do they work?
I've run into audits on every queue except the close vote queue, on which I've done nearly 300 reviews since the audits were (supposed) to have been put in place.
What are review tests (audits) and how do they work? claims that close vote audits "present a reviewer with a question which the system has determined should be open or closed based on various criteria." I have seen such audits only in the reopen queue.
Over at the very similar question Close votes review audits, it was asserted that "not all audits give you a 'congratulations' message". This doesn't agree with the answer at Add a positive feedback for all types of review audits, which says that "congratulations" messages have been added to every audit regardless of queue.
I've never seen "congratulations" on the close vote review queue. Furthermore, I just checked the 40 close vote reviews I did today, and not a single one is shown as being a review audit.
What's going on? Are there really no review audits on close votes? If there are, am I somehow exempt from them? If there aren't, why is that? It seems that close votes are just as deserving of audits to avoid abuse (e.g. always blindly voting with the closing majority or always leaving open).
