In my case (game chat), if it would even apply to me, I'd simply scan messages containing slurs or political key words, and if detected, not store them. They will only be displayed. Meaning everybody will have a "clean" chat stored.
In order to find it out, they'd have to buy my game, shout nigger into the void of empty space, screenshot it, and then check the messages I stored.
And I can say uuuuuh sorry goys, it's a feature, because for the pussies who activate "sensitive mode" it will be displayed with asterisks, and somehow I decided not to store those messages.
