I wont even bother writing them. If I'm not mistaken China doesn't have a law against copyright. I'm sure there are tons of hacked games on other chinese markets too.
Uploading your own won't help you, because some of them change the name of the package (at least that's what they did for one of my games).
Some have additional ads (notifications along with my admob ads), others are totaly screwed up. For instance, one of my game now runs in portrait mode instead of in landscape
They may even change the name and the icon thus making it impossible for you to find it.
I'll just leave it as it is. They probably don't generate much revenue anyway. If I make 1 - 3c per click on AdMob, they must be getting 10 times less.
