Recently the question Is there a minimum mass is required for light to be noticeably bent? popped up in my review queue because it has a few close votes/flags. One is for "Unclear what you're asking" and the other is "Primarily opinion based". I thought about hitting "Skip" but ultimately I decided to vote "Leave Open" because I don't think either of those votes is accurate.
But now I feel guilty and I wonder if choosing anything other than "Skip" was a conflict of interest. I have an up-voted answer in response to the question and I think that makes me a really poor judge of where the question should be closed or not.
Is there a generally accepted convention about conflicts of interest like in this case? Should I have chosen "Skip"?
