I wanted to ask why there is the option to leave the room during a game. It has happened to me several times that opponents who no longer have a chance of winning, or even worse, are leading by a large margin in games, and when they can draw or tie, use this "super joker". As I see it as gross unsportsmanlike conduct, I wonder why this move is even allowed without punishment, i.e. without the corresponding loss of points? Thank you very much
