I don't get that any of them identify themselves as higher status than they are. Certainly Anna, Alicorn, and Julia have very high community status.

Someone should test this; create sockpuppets with male and female names to see how common and critical replies are.

My prediction (based on prior expectations and observation of behaviours directed at existing lesswrong members) is that a female username will tend to be the target of less rivalry motivated aggression than a male username but can anticipate far more challenges and status attacks from female usernames that identify themselves strongly as high status.
