Is saying 'cause youre a bad chinese player' perma bannable?

Ironically, the person I "flamed" also got banned. He lost first blood and was super toxic (talking about how mid didnt move etc and flaming me). He was saying the N word and I said hes a stupid chinese player because of his name. Somehow even this kind of 'flame' is bannable. This ban system is such a joke
