I think that there should be a minimum set of requirements that needs to be acquired by an individual before a fleet can be made, and then a minimum set of requirements for the fleet to remain in existence. My suggestion is that no player under level 40 or 50 can become a fleet leader or create a fleet. This will stop players from making fleets just to stop others from using the names. Also, a fleet must have a minimum of 5 members in it within 1 week of creation for the fleet to remain in existance. If a fleet is created and does not have 5 members in it within a week, the server automatically disbands the fleet.
