The Hunger Games

My question was from the perspective of the rules: does the second player violate the rules in such a case or not? And does a player have the right to deliberately break the rules, and what consequences await them — a loss is obvious, but is there something more serious or not???
Since this is not a 2v2 tournament, it seemed to me that the second player does not violate them. But if after the game they also conceal these actions, and even conceal the Dragon Fly Hive — then that means they themselves decided that these actions were dishonest. Therefore, I hope there will definitely be no such players.
