In the rule “Relationships”, add a subrule named “Accusations” with the following text:

An Accusation is a Story Post where the title begins with the text “I accuse” followed by the name of a Wordsmith and no other text following that name. The author of an Accusation is known as the Prosecutor of that Accusation. The name of the Wordsmith in the title of an Accusation is known as the Defendant of that Accusation. As a Round Action, a Wordsmith may post an Accusation. An Accusation is either Open or Closed and defaults to Open.

At their earliest convenience, the Puzzler should perform a Ruling on the oldest Open Accusation. A Ruling is an atomic action with the following steps, where the terms Prosecutor and Defendant apply to that Accusation on which the Ruling is being performed:
* If that Prosecutor was named as that Defendant’s Rival at the time and date of the posting of that Accusation:
** That Prosecutor gains 1 Point.
** That Prosecutor is removed from that Defendant’s Rival.
** The Puzzler must post a comment to that Accusation with the text “X is guilty” where X is that Defendent.
* If that Prosecutor was not named as that Defendant’s Rival at the time and date of the posting of that Accusation:
** That Prosecutor loses 3 Points, to a minimum of 0.
** The Puzzler must post a comment to that Accusation with the text “X is innocent” where X is that Defendent.

After a Ruling has been performed on an Accusation, that Accusation is Closed.

If you suspect that someone named you as their Rival, you could accuse them and stop being their Rival, but if you’re wrong, you’ll pay a penalty. The Points gain is not as large as the loss because of the strategic value of removing yourself as their Rival.

My intention is not to weaken the Rivals mechanic but to add an extra layer on it, but I’m open to arguments that it goes too far.
