I get a message saying that I am banned from a particular chat room. When will this ban expire? I also seem to be banned under chats that I haven't even entered. Is this just the same chat room but with a different name? Or am I able to be banned from chat rooms before I even chatted in them?

Under old chat the bans would expire when the room went empty and subsequently closed down . . . is this still the case?

The room is called "The aliens are not really coming".
