Thanks to gippo, he agreed to remove your ban.
1.If suddenly admin or more teammates calls you out over VOIP then something is wrong and best to take action and respond quickly to resolve any misunderstanding (to avoid being reported, kick or ban)- applies to every player also
2.If you are planing to do something very risky in critical situations like that session when we hanged only on 2 flags and every tactical placement of MHQs matter so we don't lose match you can even just send message in side channel and inform teammates of your actions so in general you will get feedback is that idea good or like don't do it man, if team agrees yes lets risk it and even if your plan doesn't succeed you get no burden of your actions and everyone will accept that. - also applies to every player
So if you just left message - [MHQ-B going to Winery] in that given moment this misunderstanding wouldn't happen.
