If you put /sp/ (sports) on the board list, maybe more people will post there?
ok so that's 3 mystery boards I know the URIs of typically that is a BO call, they can unlist the board in the settings if they want iirc it doesn't show up in the overboard either at least by default t. not "staff"
ofc I have no idea the history of how all these boards even came to be, if there was a period of open creation or not
