I noticed something about review audits:
When it's going to give me an audit, the page says, "Loading next item" for a long time (>4 seconds).
Otherwise, the wait time is <1 second.
UPDATE: This was not a temporary bug. It is still occurring. Makes defeating audits easy.
Confirmed by @Videonauth(1) & @Wilf(2):
No nothing new, I usually know as well by this that an audit is coming. Noticed that long time ago
I've noticed it occasionally previously
