Why does every game have a profanity it’s annoying

I was going to redone my car making it look better and I got to the nameplate and my plate stayed Red 666 then when I change it like Death or Killer or Daniel or Purple it said the **bleep** of “text contains profanity, please change to continue” besides Red 666 count as one too but they kept it then when I put text on my side of my car that is “drive fast” it said profanity…. Like I know heat allows you to customize your car to make it cool but without putting words like I’m not putting bad words or inoperative words just making my super car cool but no “every stupid words count as profanity” NOT!!! Can you just get it fix or say why the heat developers do this and I try to put the nameplate on my car to say heat and the more **bleep** is “text contains profanity” when they put the name heat
