I remember reading a thread on another forum about this and decided to test it out .
Sat my guild was getting set up for its usual Sat night raid on a horde town (125 hks an a little over an hour btw ). Usually we fill up a whole raid plus so we were inviting other people that wanted to join as well. We were preping when I typed "/em pickpockets 10 silver from you." This shows up in orange text and kind of looks like a general message.Sure enough soon I got a couple of people not from our guild calling me names in tells, etc. It was pretty funny actually! It was amazing how fast it escalated.
This one person in particular kept calling me names. The last part was when my guildmates started /em stuff about me, like "soandso puts Kirwin (me) in their pocket. (I'm a gnome). This guy kept saying in local, "Yeah, get him he stole my silver"
Classic. Then we commenced to hand the horde at Hammerfall there butt for 1.5 hours until they finally got some lvl 60 mages to show up with some giant earth elementals to break it up hehe!
