I've just seen a topic which is called "only joking" and two of the last five threads are either racist or disablist threads.
And of those five threads, one of them goes back to 2004 so the board is barely ever used.
Isn't it time to do an audit of topics and delete some? There's all sorts of random stuff out there - do we really need it kept forever and ever?
Is it time also to consider an expiration date for all boards, not just chat? Maybe one year for all topics apart from Classics?
