Don't try and parrot racist shit
I don't care how much you like BRO%%%%FISTER42069 and his extreme beef with whatever ethnic group he has a beef with at the moment, if you say racist shit in the game chat, you're going to get banned. If you try and mask it somehow, you're still going to get caught, and you're going to get banned.
I lost count of the number of accounts that have been banned in the past few days alone, because people want to parrot some stupid bullshit they heard on some dumbass' Twitch stream, and then they get shocked, SHOCKED, that such language is not tolerated in League and has never been tolerated, and that it is punishable by either a chat restriction or a straight up account ban.
