They did recently when a guy from the Phillipines used fake docs to try & get his (over 300 bitcoins) winnings.
Cloudbet paid that win so I dont see why they wouldnt here.
I think you are referring to Swofty's
case and no the guy from the Philippines didn't use fake documents but what happened is Swofty who was trying to claim the 330+ BTC withdrawal asked help (because he was based from USA) and made it look like the guy from the Philippines was the one claiming it therefore making him the one to submit the documents in order to claim the BTC. Swofty admitted that it was a mistake on his end and the problem was resolved.
At that point, I got very scared. I went from really excited about my winnings to very, very scared I wouldn't get any. I have a good online friend in the Phillipines and I asked for help. I had him give his documents and ID that said the account was from the Phillipines.
I should have been upfront about my situation from the start and this situation would have gone much more smoothly.
