Are you 100% sure that the withdrawal issue came from you sending your funds to a gambling site? Granted that you were able to send it to another exchange, but that was after the support team saw the problem. Probably just me missing a few details but that's what I understood from your explanation anyway. Try asking support what the issue was exactly, it may just be on their side or something. I hardly doubt that exchanges would ban transactions to gambling sites since they aren't even government-controlled in the first place, why would they even care.
