Thanks for posting this. There are actually people who participate in these scams knowing full well they are scams in the hopes of getting out before the inevitable collapse. They see it as a game, but don't seem to consider the serious ethical issues with knowingly supporting a scheme that will defraud many out of their money. It's one thing if you put money into something not realizing... It's quite another to do so with full knowledge, and especially, to influence others into doing so. Like you say, plain old right and wrong.
