By publishing on Google Play, you agree to adhere to Google Play's Developer Program Policies and Developer Distribution Agreement. Google is not required to send you a warning prior to suspension or termination.
If your app has been warned or removed from Google Play, we will send you a notification at your registered developer account’s email address. It's important that you read it.
A warning tells you that your app is close to being suspended. Failure to address the issue, or launching a second app that does the same thing, will almost certainly result in your app's suspension, or even termination of your developer account.
