It's kind of a fun mechanic to be able to name your battleships/railguns and then see them perform in the paper. Unfortunately other than the day they are built all the locations where the tiny bit of customization appear to have been removed from the game. It's clearly not a huge deal but game players rarely like having things taken away from them.
I do miss seeing the notices in the paper or when you review a fleet it used to tell you the names of the battleships in that fleet. IIRC even when a ship was sunk or when it killed another battleship I believe there used to be a notification. I can only assume that some players where abusing the names in a way that breaks the rules or was just too vulgar but effectively you're punishing the group for the actions of the worst behaved. Why not just put a notice on the naming screen that offensive names will result in the ship being removed from the game or something along those lines. Harsh but effective and punishes only the offenders.
