Why did Natsuko, the ultimate gamer of the king game, not die after receiving a text message?

This question was related to the plot of the novel " The King's Game Ultimate Natsuko." In this novel, text messages were an important prop that could affect the direction of the game. The content of the message was usually about the game's internal information or rules, such as " Congratulations on obtaining the highest level in this game " or " You have been selected to participate in this game's special event." This information could help players understand the rules and rewards of the game and thus better play the game. In the game, Natsuko received a text message telling her that she had been selected to participate in a special event of the game and would receive a generous reward. Natsuko was very happy and began to seriously prepare to participate in this event. However, Natsuko did not play the game according to the rules. Instead, she tried to use the loophole of the text message to cheat. She tried to gain an advantage in the game by sending messages to other players. After her behavior was discovered, she was reported by other players and banned from participating in the game. Although Natsuko received the text message, she did not follow the rules of the game and did not receive any rewards. If she played the game according to the rules and followed the principle of integrity, she could obtain benefits and achievements in the game.
