From what I know, Galaxies doesn't let you do that unless I'm misktaking, same thing with online play on Battlefront.
I'm just going based off the two mmo's I've played, WoW and City of, both have things against harassment, Galaxies does too IIRC but I don't know how to access it.
Anyway, I don't hold out hope for Kotor 3
Agreed, that died as soon as they announced the MMO...
but it is nice to speculate on what KOTOR 3 could be
