Hi, I received a message from ftx saying that my eth was in contact with an impermissible wallet and it falls under FTX prohibited uses and for that reason my deposit is under review. The withdraw was from a gambling site that I won from betting sports. I read under FTX user aggreement that illigal gambling is not allowed but where I am from off shore gambling is allowed (grey area). They are asking for me to prove that the wallet I used in between is mine.  Am I giving them cause to close my account if I give them this proof? I really want to keep that exchange since it is one of the best out there.

If anyone can give me advice, I would appriciate it.
Thank you
