Back in the days, when for whatever reason i visited a lower level area and noticed some alliance was around, I used to try and trick them by flagging myself, sitting and typing /afk.

They would circle around a bit, and decide that I was an easy prey (since afk) and attack me (flagging themselves)
unfortunately they would quickly realize that having the /afk tag didn't mean the player had to be away from its keyboard.

so basically they attacked something red, and died from their own stupidity. I don't see the difference here.
