Ban hammer madness

So I’ve been playing for a while this morning and after another warzone loss I left matchmaking and then got a screenshot saying silent cartographer banned for 12 hours WTF?

I’d had a warzone xp active and it showed as active on every match where as with arena bonuses they disappear after the game, would this have caused it?

Dont know what’s caused it and not only p***ed that it’s happened but want to avoid it happening again if I don’t know why I’m getting banned?

Maybe a little more info when passing out bans would be helpful?

I got this same thing. I left after the match was finished during the transmission (as I always do, I have never left during a game) and got a message saying I have a 69 day ban. But, I can still play?

There I definitely something wrong with their system.
