Eh, just saying, on my opinion of dealing with bullies, I'm not THAT old. I still remember school. And I was in all the advanced classes and was TINY (I was only 4'11" when I started high school). I got picked on a good bit until people learned it wasn't worth it because they would end up getting laughed at.
Different things work for different people, but honestly, the whole "ignore it" part never worked for me, and I never really saw it work. And it definitely won't work in the context of an MMO. I don't think I ever saw the same group of griefers more than once (if I did, I didn't remember), so how were they supposed to learn that I wasn't worth messing with? Actually, almost all solutions to being dicks revolve around some form of memory of each other, and in an MMO, unless the player base is TINY, that just isn't happening.
And anyway, that kind of stuff was only half the problem I had with MMOs anyway. The other half being the seriousness and dedication so many people take with it. So few people seem to play an MMO casually. You either don't play, or you have multiple max level characters and are grinding equipment.
