@guaroz,
3. Don't vote either and keep playing.
@Riversong,
If your question was specific to this game, then as Guaroz pointed out, it is frowned on in this site. However, if you are asking about the site etiquette, then you should simply have kept it vague and not included the name of the game. In my opinion, this would have been ok. But, there might be others who disagree.
As far a site etiquette for drawing, cancelling, or playing on after NMR's or CD's. I am not aware of any defined rules or guidelines for this. I think each player makes their own decisions on these. I tend to want to play on, but consider cancelling/drawing if I am unfairly advantaged. This is particularly true on larger games, where NMR's and CD's are common. On smaller games, where the impact can be huge, I am more inclined to end the game.
