I do not think OP would use his or her real account for such advert here as this post looks so awkward.  OP knows the gravity of this post he or she has made and would not take the risk of revealing his or her identity to the public. So coming up with a quick story losing or unable to access the original account would need OP response. This type of situations are very sensitive because of the amount and manner at which it was gotten. If OP had used his or her real account,  I believe by now OPs real identity would have been revealed and possibly the casino might likely be identified.
