How do you unban yourself cod5

ok well i have neverrrrrrrrrrrrrrr been banned before from cod5. but when you get banned from something that means that you did something wrong now treyarch listed you a banning ticket or something like that for doing something. say you modded a controller. well if treyarch caught you. in the message they should had told you what it was for and how long its going to be. now the way you get unbanned is probably impossible if your trying it during the period of time they banned you because they probably saved your e-mail address and settings that you put in for your live account information. so you probably will only be able to get unbanned when you go to your friends house or something. what ever you did you need to learn from and fix your mistakes. hope that helps.
