Haha, I remember those TLK fanatics... And of course, when they get out of hand I just block 'em.
But, most of the time I just watch because I'm one of those people who likes to sit and look at things. Entertaining things, that is. Especially the continuos godmodding, powerplaying, and auto-hits you see people use while fighting over something that was created before 8-yr-olds were even born, not that any are adults.
But, of course, if they rip your preset or character off and say that YOU stole it, then, well, that is a different situation. But, all in all, both problems would cause absolute disruption and havoc among players who shouldn't be in the quarrel.
