Kixeye's true release is March 2012 (or so they say) One big thing they added to bases is User ID. So even if you do not talk in COMMS people can still click your base and figure out your User ID to see if you are new or old.
One way to get around this is a REALLY LONG name. When you have a long name for your pirate name it sort of pushes the ID out of the little box so it is unseen by other players. This is the fix for now. I and a friend have been looking into how to make your user ID lower (like in the 1 millions or so) So it will be impossible to figure out when you started playing the game.
Hope this helps everyone out there.
