The OP said he lives in a dorm with many people and used his own money to win. So basically you saying its ok for FJ to steal his winnings and his "DEPOSITS" too? Is that's what you are saying?
If that is case than it won't be so hard for him to prove ownership of 1 account and other users to prove ownership of their accounts, right? Besides, he said he is living with 300 people and they all share 3 computers it means that IP is the same. Is IP the same?
To be honest this looks like 1 person, but I could be wrong:

I don't think so. Email conversation is much longer than 48 hours, and accounts signed up on 14,15 and 16. Feb so I think it is very strange that they all signed up and complained at the same time:

But as I said I can be wrong with this.
So, I think it is best to wait fraud department to finish with investigation, if everything is fine then there won't be reason to hold his/their funds.
I can vouch for jborn as i've know him for a while outside of bitcoin talk, i told him complaining on here might get a better response after he mentioned their support seemed to be ignoring him. I'm not sure whats going on with Fortune Jack at the moment as i've never had problems with them myself. Since all these accounts appear to have been registered at similar times, i wonder if they just linked them together on that basis?
