I think you didn't quite understand what @seleme meant.
He meant that at the moment these documents are not required, but they can be when someone manages to win a large amount. He even gave an example that some casinos require documents to prove that you were really in the time zone according to your IP login time.
Again, this does not relate to my original reply (which @seleme quoted). I'm not sure why you 1xbit shills are repeating the same nonsense that has nothing to do with the current discussion? Please read at least a few posts before posting your comments.
