There are no threads on this, there is one but it misses the whole point of this. If you're bombing halaa (2.2.2) and you just lost the wyvern camp, press escape button and press LOGOUT. Log right back in and boom your pvp is gone, therefore you'll be non flagged and alliance / horde wont be able to gank the living daylights out of you.
If you're in a group, I suggest having someone make it a raid, because when in a raid and you d/c you dont get booted from group but you will in a regular party. This is extremely useful for halaa raids because when you land they wont be able to attack you and you can "run off" (really to another camp) and they'll just think you left.
I hope this helps all you die-heart halaa raiders! Use this while you can will probaly be nerfed in 2.3!
