Whenever I share stories about Silent Heaven, it feels like I’m always doing something different, and yet it works for the game.
In this case, we have a policy for a right to OOC privacy. That is, nobody is required to share their OOC identity, but you can share privately with people you trust.
Staff are marked as staff in the Discord chat, and they, too, don’t have to reveal who they play. I also strongly enforce a rule that staff cannot be on their staff account at the same time they’re on their alt, which eliminates a lot of mischief that could happen. They also have to mark other characters that they interact with frequently on a “conflict of interest” list, which codedly hides all information, notes, jobs, and requests of those characters. This makes it so they specifically give the most RP to the characters they play the least with.
I can’t imagine this would work for every game, but it works exceptionally well for us.
