After just having read the other thread here about the major cheating scandal, i really don't care whether you get your money or not. Perhaps you should have also thought beforehand how you would get the money if you ever won. If 99 % of players have no problem divulging their true personal information when registering, why can't YOU? Frankly, none of us particularly LIKES giving out personal information but it's part of the deal. You treat the pokerroom/casino honestly and hope that you will be treated honestly in return. When registering, a new player signs off that he agrees with the T&C and that the information submitted is true and accurate. And just because it's done over the Internet, it's still a contract.
It's actions such as yours (be it deliberate or just stupidity) that creates problems for others, possibly for other players from Russia or for other players period. Because of the major cheating scandal, it shouldn't be a surprise to anyone that pokerrooms will request much more information, such as ID documentation, when registering and certainly when withdrawing funds. It probably will become a pain in the neck to withdraw funds and it will take much longer. Then, they will discover that the cheating and lies were even much worse than they ever thought and lots of underage kids playing at the pokerrooms. Then there will be more stringent requirements placed on players just so that pokerrooms (who are now consolidating and going public) won't have major exposures on their hands.
I sincerely doubt the pokerroom will let you change your registration name and is not likely to pay out your winnings. If so, let this be a lesson to you and sign up with future pokerrooms in accordance with the pokerroom's requirements.
