In any case, you didn't really lose anything, you just weren't able to withdraw what you won with free money, so it's not that bad IMO.
Exactly, that's free money overall why OP cried it here by not paying that casino.
The casino will think that he was abused the faucet because he was created another account that linked to the first account that the account made.
Op had successfully withdrawn 6mbtc and I think that is free from the faucet without having any capital to risk, so that is not a problem after all. There's a policy from the casino that users cant able to withdraw from the faucet if they will not have any amount to deposit.
