When people were banned they were sent to the black hole. When they were unbanned they were able to leave and enjoy playing again. This led to people getting banned purpously to see what the black hole was like. To stop people from purpously getting banned Jagex created a mock black hole were unbanned players could go. To get into the black hole you would talk to Thordur who would sell you the disk of returning for 10gp( now around 10m )Soon players were being tricked into dropping their disk of returning while inside the black hole and would be stuck untill a friend brought them a disk. So Jagex got rid of the black hole but kept the disk of returning even though it has no current use.
