Just want to throw out there that a 2-3x wagering requirement on deposits (purely deposited funds, NOT any bonuses) is pretty common for sites like FortuneJack (I know BitStarz does the same thing as well). When I asked BitStarz about it, they said it was to prevent/mitigate people from just using their site as a money laundering service. In other words, they don't want people to deposit only to make 1-2 rolls/bets and withdraw in order to use their site as a means of attempting to obfuscate coins that were used for illegal services, stolen, etc..
I haven't played on FJ in quite a while, but when I did (~2+ years ago for a 1-2 year period), I never had any issues with them.
People do really miss out these informations about wagering requirement and they do only complain when they do already experiencing such problem. Not only Fortunejack do have these terms but all of gambling sites as well due to the same reason. They dont really like for them to be used up as a possible medium for those depositors who just deposit and take out the money for sole purpose either for just mixing up the coins or to launder money,as simple as that.
