To preserve signal, you need to cut them out.
No matter how many porn boards were made to keep the porn dumps from taking over /b/, it still happened. Therefore we give up on trying to clean up /b/ and instead make a new /b/ for those who want a random board that's not just porn.
/bant/ is the second nijiura of 4chan and it's approximately a decade late. Moreover, while technically being a nijiura of /int/ there are a number of other boards in need of a flipside. Thus you get a topicless random board.
