To help further with this, I have reviewed the suspension but we will not be able to lift it. The account was set up to traffic APK files, and among the handful already present are at least two that are copyrighted and not authorized to be redistributed through unofficial websites.
Along with this, a proxy was used to access the account. Said proxy usage has caused this account to be irrevocably linked with other accounts used for malicious purposes, which is likely why you're being blocked from signing in - given the infringing material on the account, this is not something we will be able to fix.
As the suspension cannot be lifted, this topic is being locked.
