Peppy labeled editing the mapset's files (which includes removing/editing backgrounds/skins/storyboards) as cheating. He does not think that playing with 100% dim compared to 90% dim is cheating (or maybe I'm wrong, you gotta ask him). "Hardcore" players started complaining before fun spoiler was in place, when peppy said not to remove backgrounds. It's been like a month or two since you could dim the background. Most "hardcore" players don't even know about the background dim because all of their stuff is all removed.
