I guess the Scunthorpe problem is still a thing. https://en.wikipedia.org/wiki/Scunthorpe_problem
Reminiscent to me of Call of Duty Warzone; it has loadouts which you can give custom names (that only you see!) which are protected with a profanity filter. Comically, some of the literal names of the guns are banned as being profane, like "MP5".
I.e. It has little to do with profanity but a lot to prevent someone from making screnshot of a loadout with a gun that looks like MP5, is named by them as "MP5 whatever" and behaves like an MP5 in some type of legal action?
