yes it matters if your going to do something to show your visible discontent with someone else at least have the descency to do it with some modicum of guts
If I knew what would I do?
well probably handle it in a mature fashion.....talk it out over pm's and at least try to see the error in my ways. Or try to at least see what would motivate the person to do that
if that did not work and the person still persisted in just being an asshole than I would use more conventional tactics
