Hi there,
It's your responsibility to connect yourself from a "safe" place and make sure to disconnect yourself once you're finished playing.
I quote once again from ToS:
It's not possible to restore a character that was deleted from an account.
Player is fully responsible of his own account access:
Password shall be enough complicated,
Don't give your password to anybody,
Connect yourself in the game from a safe place,
Don't delete your character "for fun".
Your account will not be unlocked, however, you are more than welcome to create a new account and join us again.
If you have any further questions regarding this ban, you can PM me.
Regards,
String.
