Ran a search nothing came up about this so here goes.
In hellfire pennisula, where the meeting stone for BF and Ramparts are there is a ledge above which that can only be reached via flying mount.
Stand up there, obviously and wait for the next group of the opposing faction to try and 'summon' their party. At this point, you are within the 20 yd range for Mind Control.
Simply grab control of the player and toss em off the edge. No the fall wont kill him. The orcs below will.
Hours of fun enjoy.
Sorry if this seems like common sense, but i find myself doing it for hours.
**UPDATE**
just wanted to let you guys know to stop doing this asap after 6 hours straight of doing this (i had a bad day) i got an in-game GM warning to cease all extensive harassment or that i would face account action
yes it was a GM i checked, wasnt some1 trying to impersonate.
apparently world pvp is no longer tolerated?
