No, it wasnt a chat ban, I just got kicked out of the sv and coulnt log into my acc.
And yeah, maybe xD I dont know but its weird that I didnt get a notification or anything, if I did I didnt see it, and I didnt even get chat baned so I guess I didnt do anything against the rules when it comes to the chat, I wasnt spaming like crazy or anything like that, just once ever 1 or 2 minutes in the public chat, not channels.
