I think CDs should be punished, not NMRs. My understanding is that a CD is just two NMRs in a row.
If you start punishing NMRs theres a risk of losing people who want to play the game but who genuinely missed one set of moves e.g. It has happened to me when my internet connection was lost.
Also my understanding is that even after a CD if no-one has taken over your country you can still re-enter the game so maybe CDs should only be punished when the game finishes and/or when their country is taken over by someone else, and all CDs could be automated to appear in the forum with a link so that they could be immediately replaced by a new player at no cost. The pot stays the same and remaining players aren't rushing to Cancel because they can reasonably expect another player to join the game at zero cost.
Then if the new player subsequently CDs they also have to pay the original game stake as punishment.
You could have a situation where a player with only 40

joins a 101point game for free but then CDs it meaning they have to pay 101

leaving them with minus 61, this person would then be excluded from playing and have to reply to the Mods explaining why they joined a game then CD'd. If the Mods accept the reason they reinstate the players points to allow them tp play but maybe with a 7-day delay.
For the person that originally CD'd they should lose the points plus pay a fine equal to the amount of points the game is worth e.g. 101 pts, they will not have their points reinstated to 100 and if this takes them into negative points they also have to re-apply to the Mods to start playing again, possibly with a 7-day delay.
