Occasionally, when I get a known-good audit in the review queue, the system shows me a fake usercard of a new user to not make it obvious that it is an audit; as it was actually posted by a higher-rep user, it lacks the "new contributor" indicator. Also, a spam or non-answer will usually have an indicator, but on known-bad audits, it lacks the indicator since it was actually posted more than a week ago.
In both cases, the lack of a "new contributor" indicator can immediately give away the fact that a review is an audit. In most cases, one has to do additional investigation to see if something's an audit, but since SE decided to show the fake usercards in the first place, I think this is sufficiently obvious enough that a user can determine if something's a review audit by simply checking for the non-presence of the indicator.
Is this a problem, and if so, what can be done about this? Should we show an artificial indicator whenever the system generates a review audit and uses a fake usercard?
