I've thought about proposing this for a while. It would be very easy to make or curate "too minor" review audits. Chances are, many of them are approved. I don't know how big of a problem it is for too many review items to be approved, but then I see items like this, and think this probably happens way to much.
So proposal is to add "too minor" audits in addition to the spammy fake text ones. Picking audits shouldn't be hard - how about ones that were unanimously rejected as "too minor" and where the diff is fewer than 5 characters (since yes, these exist I think in abundance).
Note another advantage is this gives us genuine reviews in the audit queue at all. The fake ones have some efficacy but I've seen people complain about them on various meta-threads, to a greater extent than say, audit close questions.
Note: the linked edit actually breaks the code by dropping a {
. All the more egregious it went approved; however I imagine the reviewers didn't notice the breaking change since they approved it... which more or less means they either 1) didn't read at all or 2) saw a tiny formatting diff and approved it instead of rejecting as too minor. So, more complicated but, still case in point.
