We all agree to keep using our in game names while playing.
I believe the only way to clear out a name is if you move to a new data center. When Balmung opened up recently, we had some new transfers from a different data center, and they said that it cleared out their friends list. I haven't tried myself, so can't confirm if true - but maybe someone else can shed some light.

If it is true, it may be an option if you're completely desperate.
