Oh no, THE N WORD!
It's almost like "He Who Must Not Be Named", if you say it the world will collapse, wizards will die, mudblood will fill the rivers and everything we hold dear vanishes. Because somebody said THE WORD. THE WORD which killed thousands of people and made countless people permanently damaged. THE WORD which destroyed whole countries and erased cultures.
Your frustration is rightful, sadly if you voiced your frustration in the chat, thats also against the rules and you get a punishment for it. Next time when somebody writes the FORBIDDEN TEXT, you should just keep playing, mute them, and report them on the post game screen. They will surely get punished for their ungodly sin.
