Hi,
In the hand evaluation forums, the suggestion is that a permission request is submitted before using a player's screen name (see: Hand Evaluation Boards -What you need to know - special rules in the hand evaluation forums, rule 9).
May I suggest using the same rule for video producers, since it seems rather invasive to me to have player's names used as I don't see it as a necessity; player 1 or player A would do just a swell surely and offer some respect to the villains of the piece?
Just a thought,
Mal.
