A couple of players in my last game were chat banned and everytime I died or made any mistake they would spam chat invites. I muted chat, mics, and pings and would still get the notification. How does this make any sense?

For context, I currently play at 27 inch 1440p 170hz and sit around D2/D3. I am going back to school soon and want a monitor with higher ppi as I will be reading a lot of text on my monitor. I used my buddies 4k 27 inch and text is so crisp...
