Sorry if I appear to whining, but it appears to me that we don't have a clear policy about reporting cross-posting. This is prompted by the following instances/examples:
It probably isn't right to draw conclusions from a sample space of 1 (I don't remember there being any other instance of a cross-post reporting flag being declined). Also, it makes no statistical difference to me whether a flag is helpful or declined, especially nowespecially now, but after you have been around for as long as I have been, getting a policy incorrect seems alarming.
I think the undercurrent here seems to be that I am (we are ?) not very clear about what the official policy about reporting cross-posting on another site is. The three issues that need to be clarified here are:
As a user, if I find an instance of cross-posting, am I supposed to flag, or simply comment and leave it there?
Does the answer to Q1 change is there is an existing comment already?
If somebody else 'catches it' before me, am I supposed to do nothing about this (except probably upvote that comment)?
