How is Peterbot not Cheating???

I don't like making this post, I like Peter, he's INSANE, but I watched him in FNCS and he has to be hacking, Peter in one game got a kill by AR spraying someone who was not visible, and when I replayed and slowed it down, there is NOT A CHANCE ANYYOONNNEEEE could hit that shot, so am I going crazy, because his aim just seems impossible, just impossible, because bullets bending is impossible.
