I don't know that I think the Gender Genie's algorithm is the best way for a human to tell, but from experience in other MMORPGs, it's often, but not always fairly easy for me to tell if a female character is being played by a female player. It's not anywhere near as easy for me to tell if a male character is being played by a male player, and WoW is played by a larger, more diverse base than Meridian was, so I'm not sure if my sense of things applies there.
