Yeah my account was wiped without warning after what I suspect was an automatic app review that Google introduced in Play Store at that time. It was just a niche hobby app but damn, it's not like I was a free user. I paid for the dev account. Good thing I had a separate google account for that.

I had some sloppy ndk computer vision running there, maybe it triggered something? I have no idea really. It's not like you can appeal anywhere. I was very busy with other things and let it slide at the time. I got away with a very cheap lesson I guess
