You have done more than is necesarry by making a post. Using the item like this will not get you banned, in case that is what you are worried about. You are using an item that you got legitimately through the game. As already stated the worst that will happen is they change the item, or a GM might ask you to stop using it in such a faction, in which case you absolutely should. But until that happens, I say you are simply using an item in the game in a unique and helpful fashion.
