Well, that's definitely contrary to the spirit of the game.
I urge you to reconsider your exaggerated claims and continue playing without hijacking the game by ultimata. This is a new game and the rules are being followed, even if miekko and Nae were justifying a strategic collaboration on something personal or long since passed. You only have an argument if miekko and Nae are playing irrationally in order to bully you — harassing you at the cost of hurting their own game — but I see no such thing on either one's part.
