In all honesty the names do not bug me at all. People will name themselves what they like or admire. My FF11 name was Kaikyaku and that was from an anime and Japanese Novel. Not all that well known, but named after something I liked anyway.
Not sure if these were mentioned:

See to me I am much less worried by all the SEPHIROTHS and more worried about the Smurfs. Tis a scary class of player that wants to be known as a smurf...
