I guess the meanest thing Ive done is in SWG Id tell newbs that all they had to do was type / QuiGon and they would unlock Jedi.

Worked every time

Back in 1998 during the original Ultima Online I “acquired” (stole) a boat and went exploring the isles.  Remember in UO except for a few areas there was no portal or teleportation means to many of the far off places.  In order to get there for the first time you had to manually visit it.  Also remember in UO when you died, you lost everything on your char and would respawn totally naked.

Anyway so I come upon one small island and find a dude there who just embarked from his own boat.  Being the PK’er that I was I jacked him, took all this stuff, including the key to his boat.  Then through some coordination with a friend of mine, sailed off with both his boat and my original one. 

About a week a later I return just to check things out, THE GUY IS STILL THERE.  He had a club as a weapon he found off some random NPC which he had to fight with his bare hands, and then had stitched himself some leather armor from rat hides that he had acquired from the rat NPCs spawning there.  He was in essence living off the island “Castaway” style because I had totally marooned him there with no way to get back….  I of course did not pick him up and never did find out if he made it off that island….

I'm a really boring person, I guess. My online persona is no different than my RL persona. As such, in 12+ years I have absolutely no recollection of having done anything mean.

But I gotta say, some of the foregoing exploits made me laugh.

I can't really think of anything mean that I've done to someone in an MMO.  I've probably trained mobs to get someone killed, but I don't remember anything specific.

I remember questing alone on a PVE server and having two members of the opposing faction taunting me to try to get me to flag and fight.  They got bored and decided to duel and just as the duel ended and one was almost dead, I spawned a special quest mob on top of them killing the low health one and leaving me unflagged.  It was a quest that spawned mobs to fight wherever you were.  I laughed my ass off at his death and it wasn't exactly nice.

Well UO had just come out and I was an immature little dork (more so than now anyways).  I logged in for my first time in an mmorpg.  Immediately I noticed someone had dropped pink dresses on the ground.  So I picked one up. 

I then spent the next 2 hours running around asking players if they, " would like to trade? ".  They always said, " Sure. " .  At which point I would put on the dress and run about three laps around their characters screaming, " IM A LITTLE PRINCESS SELLING PINK PRETTY DRESSES!  BWAHAHAHAHAHAA!!!! ".  Then I would run off.  I probably did this to a good 40 or so people. 

Yes that was my first few hours spent in an mmorpg.  I don't know if that could be classified as being "mean" but it sure was something.  Why did I do this?  Heck I don't know.  I have no idea.  It's lame, weird, non sensical, and outright special.  I was a kid.  Whatever....

I went on several of my friends accounts in this game I play and called this girl I didn't like a "giant pink whale" because she always wore tacky pink looking clothing in game and because I didn't like her...

I realize how mean that was now.
