Why don't you complete KYC first, and if after completing KYC you can't still withdraw, then you can now complain about any inconvenience and attempt to steal from you, as far as i know Fortunejack is not the only casino that requests for verification, if they have changed their policy to include it, i feel customers have to comply or choose another casino.
Because this is my right not to complete kyc and they are made it possible for people to use their website like that.
If I wanted to do verification I would use casinos that doesn't give option to avoid kyc.
This case does not have enough proof for you to say Fortunejack does steal coins from people, because that is a serious allegation, the op of that topic has not provided strong evidence for any member to verify what they said.
I can easily show my account having zero balance, nothing showed in transaction history, and I am not some newbie member to made up fantasy claims.
I don't know what else to say than stolen coins when balance is zero and no withdraw transaction.
