It is actually a halo4 ban. I found out today when I got back on, the message showed up again. It told me to go here http://www.halowaypoint.com/en-us/games/halo4/ban/, so in fact the mods do listen to trolls.
So I just got an in game message saying my voice chat was banned for a week. Why did this happen? I never even use voice chat lol I had a group of kids harassing me the other day and constantly betraying me/ saying they will get me banned ( I have all messages from it) so if I did get banned because of these trolls I would like a refund for this game. Any game where the creators and mods use ban hammers to listen to trolls to punish people playing by themselves is no game I want to be part of.
