I always find it funny when people think that their discord-channel no matter what they do there is their right to have; not it isn't. This was maybe the case back then when you had your own teamspeak-server, but discord like everything made it easier, but also you are dependent on the service itself. And no, discord will definitively NOT go against Activision for some boosers.
And yes, personally i'm happy when they go against the boosting-fraternity.
