Not fair indeed, but sending in KYC documents that aren't your own are either illegal or should be illegal. I know you feel screwed over and rightfully so if you got surprised with KYC but stooping to their level won't help the situation. Besides being a bounty hunter you should now expect that you won't get all of your assets because things like this are going to happen. There will be scams and there will be surprise KYCs, this is the life of a bounty hunter sadly.
