I recently got attacked with my warrior alt by a horde warrior named Exmen. Unable to switch my pvp off,he started attacking me when he saw me. I told him to stop (as seen in screenshot,chatlog) which he answered with ok (chatlog). Then,he started attacking my mob. I don´t know if he tried to steal my kill. After I killed the mob, he started attacking me again. I turned around and di this screenshot:
As you can see,he is targeting and attacking me,and it can´t be an accidence,because i got thunderclap buffed,running out in one second.
You can also see my nice modified Interface

(if you want the addons or the use of them,pm me or /w me ingame)
