CoD 4 how to get unbanned?

hy guys,

how i can get unbanned from a call of duty 4 cracked server.
it write's "You're permanently banned from this server" or something like this.

It's there a soulution how to unban myself?

thx for answers.

No. Unless you hack the server itself, which is practically impossible, the only way you're getting unbanned is by either changing your CD key or you get on your knees and beg the admin to unban you.
