Bitcoinpoker.gg found some people create multiple accounts to abuse their freerolls. Of course this is not a good result for their promotion.
Satoshicardclub also stopped their freerolls and their weekly rakeback, I dont know when they stop it but seems that there is no more players in this site.
One more site that I think also stop their operation is BetVIP.
So I just wanna suggest you to play at GTD tournament or ring games instead of freeroll..
From www.bitcoinpoker.gg i can't withdraw 0.0138 btc .. and i don't have any connections with multiple accounts..
