Short answer, nobody's reported her because nobody has run into that kind of behavior while she's been in Melodies. I've never even encountered her character and had to check the taken list to even know who she was, it's a big game.

If somebody is going to report her, I'm betting the mods would want to see some current behavior that's alienating the other players, rather than older stuff. It's easier to not hold a grudge about second-hand deets we got off wankgate?
