Just because the server is closed doesn't necessarily mean they're gone. from Jesse Schell's post on TTC forums. "I am sure that the folks running the game will carefully back up the database, in hopes that one day, the Toons can rise again. Whether that will actually happen is another matter, but putting in terms a Cog can understand, there is real cash value in the Toon database -- and Disney knows that. Think of it as a long term "Frozen Assets." If, one day, the server was to reopen, you would be reunited with your toons.
EDIT: Just because the higher-ups don't care doesn't mean that the lower-downs on emails and phone lines don't. Some of them even cried. They care.
