Sad...
I got an e-mail from Battlestate Games as follow,
Remember:
The date of the ban may differ from the date of the violation.
If you were banned for using cheats, you may not be able to play EFT on this computer anymore.
You are fully responsible for the game from your account, so no matter who uses the cheat on this account, the account will be blocked.
If you think you was falsly banned, please contact BattlEye support. If they didn't help you and BattlEye left the ban in effect, then this case cannot be reviewed.
OMG
Should I prepare a HWID spoofer?
If I don't, and if I purchase a new account and log in from the launcher? perhaps I will be banned again immediately? Haha...
