Unless you're allowed to say slurs without being banned, your forum will be overrun with bots. The sanitation of the internet is the perfect breeding ground for brand-safe AI promotion bots.

4chan has bots too.

Curious how you came to that conclusion. Anecdotally, places where you can slur to your heart's content like /r/conservative seem far more inundated with bots than other areas of Reddit. I feel like that's really saying something too, because Reddit has a really bad bot problem overall.
