I just failed a review audit by attempting to comment on an answer the system considered excellent. I thought it was fine, not great and was going to add a comment asking for a little more context in the answer.
Now this answer has 17 upvotes; which is why the system thought it was excellent. But this was way back in 2010, and as we keep telling everyone; standards have changed since then and things that might have received upvotes in the past might be closed/down voted today (in my opinion I think this would have stuck around at 0 if posted today)
I would like to propose that questions/answers are only used for audits if they are (say) less that 1 year old.
