Got Banned for today because I joined(?) a match

Got banned a few minutes ago because I was idling in a game. First of all, it was just quickplay, and second of all, I didn’t even join the game. I was in a quickplay lobby, but when I joined, the loading screen would just be there for about a minute. That happened multiple times already but everytime I would just get back to the menu screen and that’s it. So today I realized that the game will just kick me out again, so I went downstairs to grab some snacks, came back with a message saying “Unable to join lobby” (as expected) and then when I tried to join a new one I got the message “Banned for idling in-game”.
Maybe I’m overreacting a little bit, but nonetheless, I can’t play Halo this evening because the game just randomly decided so.
Why you do this 343?

Feel free to use the appropriate ban thread linked below. If you were banned for idling, you were idling. if I have to prove it I will, but I’d honestly prefer you not make me clip it to show you were doing what we both know you were.
