I've occasionally seen individuals in the Chamber of Lost Souls that I thought might be in one of my games.  I realized when I went to go look that I wasn't sure if I'd actually be able to find them.

If someone's account is banned, do they disappear from the games that account name is part of?

No, it is up to the GM to remove the player (we do not automatically remove them, as that would also remove their characters, and the GM might want to keep using those).

Thank you, that's what I was wondering about.  This time it was just a person who applied to the game but didn't actually join.  I was worried about what would happen to a player's characters if their username was cut.
