Here is a really easy fix for the whole post editing fiasco:
Each member of a team must submit any and all deck codes to the PvP Organizer immediately before their match starts. That way the PvP Organizer has a copy of the code to match to the post in case the person actually does need to edit their post. If at any time the decks do not match what was sent to the PvP Organizer, punitive measures may be taken.
Here's another bonus with my proposal. Since the PvP Organizer would have access to the deck lists of each team for every round, it would be in the event's best interest if said PvP Organizer was not a player in his own event. Even without my proposition, when a PvP Organizer is playing in his own event, it creates a conflict of interest that potentially harms the integrity of the event. I'm not pointing fingers at anyone in particular, because this has been a practice on our forums that has bugged me for a very long time. It needs to stop. If we have a dedicated group of PvP and Tournament Organizers, then having a rotation would mean that no single person would get stuck having to run all the events without ever participating.
