The mods have always been good at explaining why when you ask. But they aren't going to babysit and tell you why each time unless it becomes a problem. They assume you've read and understand the rules. They aren't secretive or shady, they are people just like us and have lives so they do what they do and move on.
Also... just the notion that anyone here cares about RMT one way or the other enough to go hunt through ss is absurd. If it isn't the first time, then perhaps you're doing something wrong. Your knowledge of it's wrongness is not a factor. If there is a mistake, then opening a dialog with them would be the best way to deal with it.
