You bring up an excellent point. If someone enters a pari-mutuel pool voluntarily, what is the harm done to that person? Lower odds? It's pari-mutuel wagering, the odds change.

And even if you bet into a CAW tainted pool, are you only harmed if you won the wager and the payout was reduced by the CAW activity?

I understand the frustration with CAW's, and the need for change, but really, what are the chances this gets to the discovery phase?

Is every participant in the class going to have to provide there betting history? Who is going to go through all that data & see what wagers where affected by CAW play?
