In “Confessions”, remove “If a Confession has existed for more than 72 hours, then any Prisoner who is its Crime’s Suspect or Accomplice is considered to have Cooperated on it, if they have not already Defected on it.”, then add a new paragraph:-

Either Party of a Confession may Threaten the other (the “Nerk”), if the Confession has existed for more than 24 hours, and the Threatening Party has either Defected or Cooperated on that Confession more than 24 hours previously, and the Nerk has neither Defected nor Cooperated on that Confession. When such a Threat is made, the Threatening Party may force the Nerk to either Defect or Cooperate on that Confession (this is the Threatening Party’s choice), by posting a comment to that effect on that Confession.

To the first paragraph of “Confessions”, add:-

The Suspect and Accomplice of a Confession are known as its Parties.
