I think only the people who are concerned enough to go in and look to see that there's nothing wrong anywhere in the map are the only ones who are going to take the 1 second to such an option, and with that the case, they've probably provided some useful feedback about what could be fixed or changed (unless the map is absolutely perfect which is rather infrequent; usually there's something that can be mentioned).
In short, only the people who care to go in-depth into the map will go in-depth enough that they might use it now and again, though it will only be applied to a few of their posts. The opposite for those who don't go in deep.
I think, instead, it would be better to just report to a staff member when you feel that kudosu has been unjustly given or withheld. Fellow staff, we have one of these in the Lounge... Why don't we have a public topic? Certainly it may get a lot of clutter, but at least such posts would be pointed our way without us just happening to stumble across them. And we could edit to note that reported posts have been checked for abuse and that action has been taken to fix the issue.
