I then attempted to login to my ‘Google Developer Account’ for
the first time. Previous to this our app developers were the
only ones to access our account to upload and update our app for us
It sounds like they violated probably one of the first requirements of the ToS not to share account credentials. From there ... really anything goes as to what that developer could have done with those credentials intentionally or otherwise.Google definitely needs to up their game here. Lifetime bans that are completely irrevocable are a completely unacceptable system for the #2 or #1 app distribution platform in the world. Such a ban should be a last resort after many, many transgressions and a result of extensive manual review, not handed out on an automatic basis. Nonetheless, developers need to do their part and also read and take serious the ToS of the developer agreements too.
