How do you get unbanned on Club Penguin?

If you've been banned, you should just wait out your suspension time. If trying to log in while banned, for example, it will tell you to wait 24 or 48 hours.

If you're banned forever, then your parent must contact Club Penguin to get your account unbanned.
It depends on how you get banned. You can get bannrd for 1 hr., 24 hr., or forever. Just wiat if your bannned forever, it's literallly forever.
