accounts will not auto-unblock after they've been blocked for exceeded limits. I can do that manually, but I must first be sure that the underlying issue has been resolved.
技术支持要求解决掉超出限制的原因，然后再回复邮件！应该就可以解禁了。
删除了被攻击或者出bug的 vercel app 之后再次回复邮件，得到回复：
After review, I have unblocked your account. Please note that this is a one-time consideration, and future usage overages may require purchasing a Pro team subscription to unblock your account.
