Unnecessary censorship

So today I was playing with somebody and his name was Boboking or something like that so I shortened it to Bobo and for some reason every single person in the chat saw that it was censored and it was censored to me as well when I turned the chat filter back on.

Now I'm not entirely sure if this is a hate slur somewhere in another language or something of that nature but I know that it's been a big thing lately with them unnecessarily censoring certain things
