hi, after many emails to GW2 support this is there final answer :
Hello,
I have performed a manual in-depth review of the termination of this account and I verified the criteria that were used to close the account. The termination of the account has been upheld and the account will remain closed permanently.
To clarify the termination for you, the account was closed for use of the third party program "Midnight". Further details or proof will not be provided as such knowledge may be used to circumvent detection.
Cordialement,
Lead GM xxx
