It seems there's been a little misunderstanding here.
As I said, Antho warned me he had to go in a private message, and I was pretty sure he informed others before quitting. Turns out they were not aware of that; this is why they reported a free win (they didn't even report the dropped game - I attached it to this post) with an "Opponent left without giving satisfaction" reason. But couldn't they just ask me why if they didn't know already? I was in #AnythingGoes during those 10 minutes.
That's it. (Note that I'm not angry on you, uI clan, not at all; I just want to sort that out.)
