Being Reported

I just got a notice that I was reported for such and such behavior and that it's been submitted to the tribunal but I have no idea what I was reported for...The only thing that comes to mind is our Poppy was being extremely toxic in the end-game lobby and once he left, I said something to the effect of, "Now you know what kind of shit we've been dealing with."

Is cussing really a reason to report? I wasn't being toxic or bad mouthing.
