FortuneJack have an active signature campaign now. Occasionally they run a sig campaign in the forum for few a weeks/months and repeat it after every few months. Generally FJ team runs the sig campaign to spread the news about their new special giveaway/promo. FortuneJack is well established casino and bookie. They have pretty good popularity. Recently FortuneJack has started a new giveaway (in games and rounds) for the forum members. They are giving away a some free spins to random users. Seems like you aren't aware of these things.

My old account was also closed by FortuneJack team without notifying me. However, I didn't had any balance on my account. Though I'm not sure, but I think they don't had the system to inform user about the account closure during then. As a result they hadn't informed you about that. Take it normally by thinking that, you bought and put some Bitcoin in your wallet in the past. Now you remember the wallet address only, but you have lost the private key .
