I am a moderator from the RP region The Fallout Wasteland. We recently banned a member for unprofessional conduct including meta gaming and harassment of other players. The banned player has since contacted us in order to have a post referencing the collapse of his nation taken down because he didn't like how it's being done. He has threatened us with invoking moderator intervention if it is not taken down.
In the Fallout Wasteland, when a nation is taken off the map for any reason, his tiles are considered "returned to the wasteland". Players can then write expansion posts into its former tiles (we have a tile-by-tile expansion system). Traditionally, players are given the choice whether or not to acknowledge its existence and come up with a rationale for its sudden collapse if they do.
The question is this: If a player, particularly one who has left the region, doesn't like how someone is doing that, are they within their rights by the rules on this site to ask for it to be taken down or changed, and/or to get official NS moderator involvement if it isn't? (Are we in need of overhauling this regional policy?) I will admit that a character created and used by the player in question is referenced in the post.
