Login On issues
What it means is that your account was hacked and then closed down by ANet.
So. You need to first run a security sweep of your computer to make sure it’s clean. Then it’s a good idea to change your email’s password just in case they got into that. After that, contact support at https://help.guildwars2.com/anonymous_requests/new to get your account back.
After you get it back you will need to ask for an Account Restoration, a rollback to a date before the hack. This is only offered one time so it’s important that your computer be clean. If your account is hacked again you will lose everything.
