I remember back on CB1 when ppl joined a clan they would change their name to include the clan tag. Here on CB2 I attempted to do the same and it didn't go over too well since some people think it is funny to take a name. I tried to suggest making a section of the name pool a Clan Tag area, it was too complicated to do.
I completely went about this in the wrong way, some players are very attached to their online handle since it is their reputation and would only change it IF they knew that no one could take it away. Why not create a Name Reservation Feature? One per account and we pay a yearly subscription for it kinda like Item naming(Maybe make their name Red too?). This could bring in more revenue for the game and players would have an assurance that no one could take their name :-)
Just a thought........
