1 day chat ban

Wtf is this. I log on sence i was gone for a few days i post in reg. Chat “WTB” such n such item and i get a 1 day chat ban? I know its supposed to be in trade but every is speaking russian. Everyone who speaks English is in general chat. Common on now i wasnt being rude or racist or toxic in chat. And i didnt spam the chat ether. Why did i get chat banned?
