I didn't make any judgement on what he was doing, just stating thats money laundering too. Most people when they see casinos talking about AML automatically think of international drug dealers cleaning billions, but they are designed to catch people laundering much smaller amounts too. As long as you keep your balance under 6k they won't touch it, and you would only launder what you needed in bank to pay bills etc, obviously 'John' would keep the rest of the cash in his house hidden in a safe under the carpet
What I see as the main problem in all this is, the UKGC should give clear instructions on it, and all casinos should stick to it. They shouldn't say 'its up to each casino what they class as a trigger, and what action they take'. They should say 'if this happens, you do this'.
They all have different procedures and none will discuss it. I've even had one rep say its against the law to talk about the AML's, but didn't answer when I asked what law. It isn't, that was rubbish. How can customers confidently play somewhere if they don't know what they may have to supply at some point in the future, to get their winnings?
The other thing I feel strongly about is how far back they can go. If I deposit today and show my deposit came from a win last week, that should be the end of it. If there were concerns where the deposit came from that generated that win, then the previous casino should have asked, not this one.
