Banned by no REASON AT ALL !!!! HELP

Guys i need you help, cause blizzard just banned me with no reason at all. When i read their email they said :
"This is a notification regarding the World of Warcraft account
[removed]. Access to this account has been permanently disabled for
exploitation of the World of Warcraft economy or for being associated to
accounts which have been closed for intended exploitation. While we try to
be as lenient as possible in our assessments of the results of
exploitation investigations, exploitative endeavors on your accounts have
ultimately lead to their closure. The recurring subscription on the account
has been disabled to prevent further charges."

I'm very very sure that i don't violate the rules, so i send them an reply saying that i'm sure that i don't violate the rules. And they reply with this word :

"It is implicitly stated on the account creation page that: This account
creation process is only available to customers in North America, New
Zealand, Australia, Singapore, Thailand, and Malaysia. When this
account was created, the standard, valid, creation method was circumvented,
thus invalidating the account and subjecting it to closure."

Which i'm sure that many people playing outside North America, New Zealand, Australia, Singapore, Thailand, and Malaysia and they create their account on their country. I need help from you guys who played and create the account outside these region. Im very sure that many people played from unsupported region, well many people on my town play WoW and they dont got banned.

Please help me get my account back.

Thank you very much
