An interesting statement made by the unnamed SANZAR Official
"...The protocols regarding such an incident - if missed by referees, media or the citing commissioner - is that the player and/or team involved has a 24 hour window after the match to lodge a formal complaint with SANZAR...."
I am not sure that the media are included in the citing protocols as could be implied from the response above.
I reckon that the media involvement is limited to their ability to whip up public sentiment to such an extent that they "remind" the Citing Commissioner to review a certain aspect of the game, the result of which may result in a citing.
It does imply that if you have mates in the media who are prepared to back you, then a member of the public may indirectly cause a player to be cited, but it is a bit of a long shot.
Generally the TV production team will pick up the act in the first instance, and the producers will then get the message to their commentary parrots that they have an interesting replay for them to comment on. The level of howling from the parrots (yes that is you marto, kearns and cannon) is frequently related to bias of the commentators.
