Seeing this I initially let out a laugh until I scrolled down and saw that they trained this using /pol/. Even as cynical as I am I don't think the world deserves a infinite racism machine.
Why not train it using a more whimsical (although still offensive) board? You could probably automate all videogame discussion forevermore using /v/.
A guy from /g/'s daily programming thread started collecting posts for that exact purpose. Nothing came of it but it's still a hilarious snapshot of that general. Sadly it's dead now.
Containment boards don't work, but my recollection is that /pol/ was nevertheless created with the intention of being a containment board. /n/ and /new/ had already been banned for racism, but it metastasized across the rest of the site. /pol/ was created after banning boards for racism failed.
