If you have been banned I believe they send an email. You will need to check the email account that you gave them as your contact. Hopefully you remember which account that was. I f you don't remember, you should be able to find out by going to myaccount.turbine.com Also check the junk folder since it may have been auto-trashed.
If you have been banned, it will probably not be a permanent ban. Keep checking your account. Probably starting in about a week.
Also, duping items =/ to Christmas. D'uh.
