Many things being posted there don't make sense in one's own game (even considering some chat entries are from the opponent) so I concluded: /zone @ pvp is for, well, all/many pvp games? If I concluded right: It sucks!
but I probably failed at concluding though, so: Who can post in /zone @ pvp?
Anyone currently in a PvP match as the same map as you, regardless of whether its in your game, can talk in zone chat. It works the same way for dungeons as well.
