Why are apps and accounts blocked on Google Play?

Question

Google

The situation is this. I had a working application that lived its own life, I did not touch it for three months. I decided to fix the bug, put try..catch and check for null - in general, nothing special. I updated the app and two hours later it was blocked!
From Google itself comes a letter that says nothing about "copyright violation OR violation of the rules." What exactly was violated, they do not write. When contacting Google, the robot answers with exactly the same answer.
Where can I read about real cases of blocking applications and an account on Google Play?
Do not offer ToS - everything is written there too vaguely, you understand.

Answer 2

I can ban for everything that comes to their mind. Just from the complaints of users who misclick.
For a unique text in which words are used, for example, on already created products.
Talking to Google is usually useless.
