I am not familiar with the site. I have no idea if they are a scam or not.
The sad truth is if the funds are being held by them on their site, they were never your funds. You just had access to an account that made it look like you were carrying a balance.
We need to gather much legit informations regarding the site itself, and relying on some accusations without strong evidence wasn't fair for the pointed person. The freedom we had here has also to be fair with the recipient of the accusations, and not only a close minded accuser who will always feeling judgemental over his actions toward the attacked manager of the site itself. If the campaigned gambling site ran smoothly, then there's no problem with the person who managed the campaign of the betting site.
