If you play Forza Horizon or Forza Motorsport, you have some freedom to personalize cars in the game, even adding your own custom designs. One popular example: players have used the feature to recreate the General Lee, the 1969 Dodge Charger from The Dukes of Hazzard, in almost every single Forza game since at least 2007. But the General Lee famously includes the controversial confederate flag on its back — and Microsoft has just announced it will ban players who use that symbol (among others) in the game.
