Recently I reported someone who was harassing 2 of my 4 characters. I reported him on those 2 accounts that were harassed, with the same report text. The GM then told me I shouldn't report him twice, because it's taking up unnecessary resources and it's regarded as one and the same incident ... that's quite contradictory to what I heard from other GMs (and I told him that), but the GM was sticking to his story.
