You honestly think that any legit company is going to publicly promise to be non-compliant with AML/CTF/KYC requirements for your benefit?
No AML/CTF/KYC laws require or even allow a company to hold funds received. If they can't identify the user, they should immediately return the funds where they came from - bounce the transfer. Exactly as if they got a random erroneous transfer. That's what all respectable AML/CTF/KYC compliant companies do, I've seen this happen at a currency broker. AurumXchange even has it written in their terms.
Failure to identify - treat the incoming transfer as an erroneous random transfer - immediate bounce back.
Holding funds is unacceptable. Bounce is the only proper way to deal with this. Huge currency brokers who deal with much more volume then BTC exchanges do this. They know the law. They can't afford their name to be ruined.
