Question about Thrones, Ivory Warhorns, and the Purge

I was wondering if the act of sitting on one of the stone thrones, or using the Ivory Warhorn, would cause the purge meter to raise. You are after all, announcing to the world at large that you are a king, are looking for a fight, and right where you are located. It would be kind of cool if using the warhorn also increases the chances that particular location is the one that gets attacked.
