Bringing war to the appstore

Clash of Clans is among the most popular mobiles games of all time. It’s also the ones with the most rip-offs on the Appstore.
Sadly there’s not much Supercell can do to fight those copycat games or is it ?
We created a dozen of accounts on the Appstore for each characters from the game and started commenting and leaving totally unbiased and honest reviews.
It didn’t change much, comments were deleted, but it was still worth it.
