Ask HN: How to go after DMCA abusers?

Recently some one from Poland (No information other than country and a random gmail address is available) filed a DMCA notice with google (Which I understand anyone with an email address can do) claiming to be owning our Icon (and pointing to Image that is not even own Icon). But as a result Google decided to take down our app (With Million+ downloads).

We filed a counter with Google and waiting to hear.

But if anyone with a email address can file wrong DMCA again an app that has More than Million downloads, how do we act on this people?
