And of course no one copied my previous message because that would be admitting that people fell for this scheme. This means that the only way for me to win is to predict that the next message will be contrary to this message; if it is, that means the message will agree with this one and consequently play into the trap I've set. And if it isn't (the next message somehow happens to agree with this message), that means the message is acknowledging the message of mine before this.
