If one person has a country name they like using, and someone else steals that name for a set, and acts like a real jerk with that country name, they can keep their profile hidden, and be immune from retribution for their actions.

I think it is honorable when people use the same country name repeatedly in individual servers. I think it is highly dishonorable if someone else steals that country name.

There is much more good than harm that will come from making country ownership public.
