Forced to change my character name for seemingly no real reason?

Okay, so I named my character "KurdishFemboy" as a non-serious, kinda memey and odd name. I have been playing PoE 1 with this name for over a month, and I have been chatting on global with no issues until today, where I got kicked out of the game and was asked to name my character again, I was baffled, thinking it was just a bug of some sorts, I went with the same name again, and after 5 minutes or so, I got kicked again, my character name was temporarily randomized and in order to play, I have to input a new character name.

I don't understand what is considered wrong with my username, I have been muted at least 4-5 times in the past, so I would assume my character's name was seen GMs which makes me wonder why am I asked to change my character name now?

I would like some answers if possible, I don't understand what exactly is considered wrong with that name
