I don't know the answer to your question, but I know the answer to a different question. If you are allowed to conceal the names of persons who receive money in a lottery, you have guaranteed public corruption gonna happen behind the scenes. No proof anybody in that town got that money, is there? Moving hundreds of millions of dollars leaves a trail. Banks are required to file forms on the movement of as little as $10K. So are casinos. So's everybody, like car dealers, jewelers, really. People would talk, and people would know. They'd also know who recently left town.
