Perhaps people who grief see themselves as Bonnie and Clyde luminaries, but the rest of us see them as small minded pricks. Leaving aside the steals from the poor of Robin Hood's M.O., most griefers don't rob from the rich. Usually, they're robbing from the poor or weak. Outlaw heroes preyed on the strong, and that's what made them loved even for their violence.

Another thing to note, outlaw heroes ran from the law every hour of every day. In MMOs there is no "Law" set up to harass these people. They largely get away with murder unless a large enough player base can pull together and track them down, at which time they might just log out. Without a 24 hour police force active, griefers might never see any form of "justice."

Suppose there were in-game consequences to their actions. Perhaps you kill someone and, when you die, you end up in jail and have to stay there for 3 hours of in game time. Maybe this time stops being paid off if you go AFK, forcing you to pace or stand around waiting for release. I wonder how many griefers would stop griefing if they had to face that instead of just a simple respawn. Bonnie and Clyde faced more than this, they faced death. How many griefers would risk perma-death for their actions?

Griefers are not welcome in most games, and they would be better games for the absence of griefers. Griefing is not a play style, it is a sociopathic catharsis for the maladjusted to feel like a big deal, and the "popularity" of Darkfall only proves this. They're not Hardcore, they're just jerks.
