I had one wallet trying to claim with 8 different IP addresses today.... for a lousy 500 satoshi.
I'm barely breaking even. Thinking about getting rid of the site. :/
Have you tried to reduce your reward in specific countries?
I'm doing and I'm doing relatively well
I don't believe that honest people should be getting less btc because some of them are scammers.
No matter what country they come from.

I do not think that honest people should have less reward, but it is a solution that has worked very well.
