I got a snapshot from Apple saying April 2nd I received over 200 downloads that day, mostly in Europe and India. My app is a highly specific application for Chiropractor's and all marketing (very little so far) has been done in Canada/USA. Any insights as to tracking real vs. spam downloads and how to stop spammers?
Well, hopefully you have analytics embedded in your app. That should also give you an idea of how many users are real vs spammers. Also, what sections of your apps are being used more often. It is not too late to add the analytics to your app.
