My initial conclusion was a bit hasty so just retyping it.
What the people did in this video was obviously wrong and against the rules.
However, the team are hesitant to punish good faith regulars, they weren't aware just how far they could go with singing and that’s an honest mistake to make considering the entire server took part in it.
We put fun before everything as a team, that’s why we aren’t going to be punishing anyone, that being said micspam is still completely unacceptable, across multiple rounds is egregious.
They’ll all be formally warned, to issue a punishment in rare situations like this is unfair.
