They have those horrible russian popup ads which equal computers AIDS, no thanks.
I'm ukrainian, and you so fear russians?
Why don't you change to daily faucets (reward every 1440 minutes) and give better reward? You say 500 satoshi, but it's not easy to get it (almost sure to earn 100 satoshi). If you offer 500 satoshi minimum daily on each faucet it will work better.
And if many people are complaining about pop-up, better to remove it, no? You can lose many users because it.
