Hello Op like what other saying above is that stake is one of the most reputable casinos here in our community and based on your complain which is they hold your money then that is your own faults it because you provide a fake KYC which we all know that once it caught by the facilitator for sure they will do an action immediately and like what they are doing right now they hold your money because of your fault.
Stake will most likely resolve the problems as fast as they can to avoid having bad reputation or I could say to restore it's reputation to being reputable, trusted and legit. There are people who sell Fake KYC documents or even real KYC documents if ever there are selling real KYC documents but I never new someone or see a forum user here in bitcointalk forum who sell real KYC documents and also have a proof of the documents that it is real and not fake. We can't do anything to stop those people from selling either fake or real KYC documents because we can only report about it and also making someone or everyone know or aware of it like advantages, disadvantages or pros and cons.
