Censored word criteria

 Hi, I would like to ask a question. While playing squad battles I sometimes change my squad and create new ones to give myself a little variety. When naming these new squads, I will usually just randomly select letters and move on just to make it quick. On more than one occasion, I've received the message that I have used a censored word. Of course, this is not a complaint, but since I never would intend to do that, there hasn't been a single time when I understood why what seemed to me to be a group of random letters contained something nefarious. So how come last night I updated opponents and get a team named after a gun? And not just any kind, but probably one of the most well known? I obviously do not understand how the system works, but I thought that anything that in any way could be seen as promoting racism, hate, misogyny, or violence in general would be and should be flagged. Can someone please explain this to me? Thank you, all the best!
