Wow the same thing happened to me[1], luckily I was awake by chance and took action after the first email, scary to think that if I was just offline for a few days my whole account could have been banned with no recourse..
[1]My app https://play.google.com/store/apps/details?id=com.lpellis.se... was on the store for several years at the time, it was called 'Android Sensors'. (Google had issue with the name, I had to rename it)
@lladnar does your app maybe have 'Android' in the name? I believe that was the issue they had with mine, I dont even think humans are in the loop at all here to give feedback.
