The wording here... makes me question your motives for asking.
Choosing not to play is done by not logging in and starting a game. There is no penalty for that. Did you mean getting yourself into a losing position and then "suffering a sudden and uncorrectable internet outage" perhaps?
How long does it last for the heinous crime of choosing not to play ?
"after a few days" .. how many days ?
"a few fair games" how many is a few ?
