it's just bad that you still didn't fix the problem with fake users. I'm pretty sure Best people are going to earn a lot of tokens and the advertisers will lose their money.
hello. Of course it's hard to deal with the fraud but we are trying to do that! In AppCoins Store app we are planning to limit the number of installations for new users. You can download only one app a day but not more than three a week. After sometime we will increase number of installations but the maximum is going to be two a day per user.
