The ratio of boy to girl isn't even close. Clans like this help with that though. One of the main reasons (To my knowledge.) that some girls end up quitting is because of the behavior of some of the boys they encounter. As even us boys know, guys online can be pretty rude and thoughtless. They say things without thinking just to get a laugh and more often than not its at the expense of someone else. Usually when a girl is present they become targets for these people much like how everyone likes to pick on kids. The point being, these kinds of clans offer a sort of safe haven away from that mess. This doesn't mean they won't be your friend though.
