It’s a mistake to assume that the term “griefing” in an MMO context only refers to a nasty act in PvP combat, such as corpse camping or fragging lowbies. There are many ways that the creative jerk can detract from the fun and enjoyment of fellow players.
Take, for example, that Tauren in the picture above. I had been waiting at this mailbox in World of Warcraft for hours to see when a small letter would spawn on the ground to start a new postal quest chain that was just added. Well, this Horde player saw me doing it, so he deliberately sat down on the spawn spot so I wouldn’t be able to click it. He remained there for an hour. Class act, right there.
And then there have been times when I’ve seen the other faction blitz into auction houses to kill the NPC auctioneers just so that it would mess up anyone doing business right then.
I’m sure you have a few examples, so share! How have you been griefed in MMOs outside of combat?
