So, I was reviewing Suggested Edits on StackOverflow. I made a determination on one edit, and the next appeared. I immediately thought "wait--I wonder" and clicked my browser's back button to check something else regarding that review. I honestly don't remember what it was, but everything turned out fine. So I clicked the forward button on my browser to get back to the next suggested edit in line. And I got this:
This suggested edit is pretty clearly a review audit, and if you'll glance at the text inside the shiny red circle, you'll see that reloading the audit in the browser window generates the error:
This item is not reviewable.
When I proceeded onward to the next edit, I was not given another audit. Edits proceeded as normal.
The problem I see here is that it gives robo-reviewers a way to cheat the audit system. It would take them a little extra time, but it would be a 100% guarantee that they would never fail an audit. It's easy: load next review, click backspace key, load review again. If you see the error, hit next and repeat. If you don't, press approve and repeat.
So... Fix? :)
Huh... Further interesting is this. I still had the tab open, and I refreshed the page (I don't know why, I think some part of my brain was expecting a new review to appear, which of course didn't happen.) But upon refresh, I saw this:
That's right--someone else got my audit, and it tells me if they passed or failed it! Curiouser and curiouser.
Also, here's a link to the audit in question, in case that helps anybody.
