We recieved reports from several people regarding problem of accidental bans. Their devices got banned because they tried to log in to already banned account of some third party user. Be aware, that if you'll try to log in to already banned account, your device may recieve a ban too. We advise to not log in to other people accounts. Same goes for the cases when users share their account with another person. If another person used their account for hacking or when their device got banned while your account connected to their device, your account will be banned too. Even if you personally have never used hacks. Not to mention that account sharing is prohibited (one the reason for that is the cases like this one).
So please, be careful with managing your accounts. If you lost or mismanaged your account as a result of your own careful actions, we won't be able to help you to restore it.
