Uhh. Well, the discord doesn't work. Not sure if it doesn't exist anymore or the invite expired, but I was trying to join and it didn't work.
Ignore my username this is an anon account
Usually when a player chats, their username will be shown before the message. Remember the username and type it into the forum. They will be banned soon.
If the bad player doesn't chat, we sadly don't have an infinite username source.
