I've asked for the Graveyard and /dev/null to be added to the list of rooms Generic Bot keeps alive. I'm not sure the bot runs on chat.SE, but don't be surprised to get a request for write access from a bot account in those two rooms. If it's added, then the bot will post a message sufficiently often to keep the rooms from being frozen. If it doesn't work on chat.SE, then the rooms will need to be kept open manually.
