Questions about the e-mailing list of the Prediction Market Industry Association

If, allegedly, the ownership of this e-mailing list was passed to the PMIA, why is it that John Maloney (a commercial conference organizer who does not belong to the prediction market industry) is still its “moderator“? And why is it that impostors are allowed to publish there? The PMIA’s unmoderated e-mailing list is an embarrassment for the whole field of prediction markets, and a shame for its owner(s).
