Strange Traffic from China

[cbtech]

Suddenly, one of my mobile apps start getting huge amount of downloads from China but there is nothing on admob. I know that Asian traffic are not so great but downloads from India and other countries atleast have some impressions on admob.

Let me ask you one question. Is your app paid or free? How you are tracking the downloads?

The app is free.

I am pretty much sure that the traffic which you are getting is spam.
