The ban you have received is either for hacking or a severe  Terms of Use (ToU)  violation.

Developers verified this ban, and this means the malicious activity has been confirmed.
These bans are intended as harsh punishments and not a slap on the wrist.
If you use hacks, prohibited software, fraudulent purchases, modified installations, virtualization tools, emulators, or change the game memory or files, you will receive a permanent ban.

These bans are permanent, and we do not unban players with permanent bans for hacking or severe ToU violations.
