A serious issue on racial discrimination and language

The language screening system has bug. It does not manage other languages effectively. Some people's words are full of racial discrimination. Look the screenshot, I understand Chinese, and understand what they talked. In this game, the purple team are Chinese and Nicoleking of the blue team is an actor, they communicate in Chinese Pinyin, and Nicoleking was trolling the whole match. He even danced with the purple team.

They are unscrupulous ！！！！because no one punishes them.

You will not let the player disappointed, right?

Please update as soon as possible in this regard！
