It's not just a matter of KYC policy, but how they handle the AML things. Do they keep the funds if the user does not want to give them the data or return them without insisting on KYC verification?
I just came across one with a new ANN here on the forum that withholds deposited funds if they flag it to contravene AML requirements. I would not be surprised if this exchange does same and withholds funds from users who refuse to KYC or if the KYC does not meet their standards. I'll of course still wait for their reply to the question, if it comes.
