Hi Jake,
Can you show us the original image? That might give us an idea as to how much of an adjustment it took to get it to its current state and whether or not it can be brought to an acceptable state with reasonable adjustments. I am assuming that you are working from a raw file. Raw format provides a lot more latitude to correct an image that is over/under exposed.
As for the current version, I think the screener called it correctly. It definitely is possible to process a photo to the point of abuse. I should know. I've been guilty of "photo abuse" in the past.

One or two of them actually got PCAs...

. One of these days I'm going to fix those.
