Do you mean how the gamblers paly with odds or bet amounts? You are right. No successful gambler want their strategy to be revealed.
but I think people want to see only their profits and losses. It won't reveal something important about them.
(Everyone has the right to hide any thing from the profile and I don't say they shouldn't hide their profile.)
I'm not sure what you mean by a "fake name"
If you mean that the site lists dummy accounts to stir up the competition in the race, I can't help you with that (anyway, this issue has been discussed before). Otherwise, it is certainly possible to trace these users unless they are hidden in the way they are, i.e. you can't get any information about them other than the amount they wagered
If you actually want to say that the site must disclose their stats to prove they are in fact real users, then I'm inclined to think that you are asking a bit too much. Really, if you were one of those big fish betting so much, would you be happy if the casino decided to tell the world everything about your activity just to prove a point here?
