Oracle 刚开免费服务器就被封号

今天发现服务器上不去了，登录账号也报错用户名或密码无效。
可以重置密码，用重置后的密码登录还是一样的报错。

咨询在线客服，客服回复：

Please be informed that your account has been terminated by the system. Unfortunately, we are unable to provide specific details. However, I do see we have an option to raise a review as an internal Appeal. Would you like me to raise one for you?

翻译：请注意，您的账户已被系统终止。很抱歉，我们无法提供具体细节。不过，我看到我们可以发起内部申诉。您需要我帮您发起申诉吗？

创建服务器之后扣了 139.19 新加坡元，顺便也问了客服，客服回复：

I would like to inform that these are not charges, these are actually verification holds that will be removed automatically, typically within 5 business days. That means all the money that was deducted during sign up will be refunded in 5 business days.

翻译：我想说明一下，这些并非实际费用，而是验证冻结，通常会在 5 个工作日内自动解除。也就是说，注册时扣除的所有款项将在 5 个工作日内退还给您。

创建的服务器在 Phoenix ，4 核心、24G 内存，账单符合始终免费，服务器创建后只安装了 fail2ban ，别的啥也没干就被封号了
