I don't quite know the full story but I will provide some information and apologise for what I assume was my wrongdoing.

Yesterday I was building with 3 other friends in a mostly empty server with 5 players. My friend makes a statement on a Youtuber, apologises and the conversation continues it eventually lead to the same person mentioning something in german (as a joke, because it was relevant to the conversation in the call) everything seems fine with the other players then i say danke (which is thank you or thanks) in german because again it was relevant. My other friend mentions a basic Spanish sentence and the conversation ceases. We continue building until we eventually log off. We try to log on the next day to find we have been perma banned.

 I know that speaking in another language is against the rules but I do not believe that saying one word in another language that was relevant to the conversation deserves a permanent ban, if any further information can be acquired that would be appreciated. And if that information provides evidence of a further consequential action then I am sorry.
