Difference was i was a zombie during the time i showed the other zombies how to kill you, in the demo you specifically walked storm threw how to get up to me as well as other zombies while being in spectate hints ghosting hints this (VI. Ghosting
1) When used ingame from same residence
A) When two or more people communicate verbally or via any other means the location and or whereabouts of enemies on a given map)no matter if they could visually see me you both communicated with players in game from spectate on how to reach my location and were i was. Also being your prior bans you both knew better than to do this witch is why it was a 1 day.
So yes you both indeed ghosted.
