Well here is an excerpt from the Play! Pokemon General Event Rules
5. Publishing Tournament Information
Tournament Organizers, judges, players, and spectators are free to publish details of play and/or the results of a tournament, subject to local, state, and national laws.
Decklists or team data should be retained by the Tournament Organizer for two months unless otherwise instructed by POP.
Pokémon Organized Play reserves the right to publish tournament information, including but not limited to the items listed above, transcripts, audio and/or video recordings or other recounts, player penalties, awards, or any other resultant information from the tournament.
So the answer to the second question is a definite no. The TO is required to hold onto those. The first one has always seemed to be a bit of gray area for me. It is clear that the larger Pokemon Organized Play can publish deck lists. They did so in the middle of larger tournaments like Nationals and Worlds, if I remember right. If you consider the contents of the deck to be details of play, then it looks like a TO would be able to share that information if they so chose.
