So I received the following message today after clicking the 'Skip' button on a close vote review because I guess I took too long to vote on it and it said it was already closed when I tried to vote.
You have failed too many recent review audits – looks like you might need a break. Come back in 7 days to continue reviewing.
While the point might be valid because I do often fail the close vote review audits (though I'd generally argue that my way of voting was correct, though sometimes I take the fail as a correction), I'm unclear why I received this message after doing something other than fail a review audit. I believe at least something is wrong because of when this message popped up for me.
As a secondary note, my record is much better for other types of reviews and so it does feel unfair that I'm blocked from all reviews when close votes are the only thing I'm arguably not very skilled at.
