Ask HN: Why are free iOS apps most downloaded form China and Russia?

I recently launched a free version of my iOS app. On day 1, the most downloads were from China and Russia. Given my app is intended for south indian classical music users, this is an unexpected demographic to be actually interested in the app.

Any insights on why these downloads are happening from China/Russia?

The last time I tried this, China and Russia dominated the initial downloads but quickly came down the list.

It almost looks like some bots are watching for free apps and download them automatically or something :)
