I'm not necessarily sure. I don't think you could write something to specifically hunt down a player.
Then again, I'm not a scripter, I wouldn't know necessarily. If there were a way, the bot would have to get the player's name and class, and then single them out and attack once it found them. Without set-up points to jump to in teleporting, it might be very hard to do, unless there was a specific place they attacked you such as on the way to Baal's throne room or the like.
