Some people dont know when to resign!

Most people think that not the win, but the good play is important; it seems that egogames is not one of them, however. Instead of following the go etiquette (if there is any over the net), he doesn’t resign in games in which he loses by a lot (50+ !!), and waits for his opponent to make a mistake or lose by time. Nevertheless, when he wins he stays in the game with hours; when he loses he leaves immediately. Of course that is his own business, but isn’t this just the wrong attitude, behaving so rude just in order to get your rank a bit higher?
