An example question of the phenomenon I've been running into recently, when working on the close-question review queue. I'm seeing lots of questions marked 'Primarily Opinion Based' with a single reviewer having marked it as such. This question, despite being bad, is clearly not an opinion-based question, nor are many of the others I've seen.
I've also been seeing a number of questions that are coming up under the 'Opinion' filter, but with no reviews on them. Is this because reviews have been rescinded? I'm not seeing these behaviors on any other filter, which is why I ask.
Is there a way to determine if there is a robot problem here? And failing that, is the opinion-based reason too broadly defined, such that it's becoming a catch-all for 'this question is horribly written'?
