Cheaters

Not sure where to report this so I just figured I'd report it as a bug. I was playing Minecraft Treasure Wars on my Windows10 and I came across a cheater. She was flying as if in creative mode and striking me without a sword with the same power as if she were in creative mode.

Her username is JayaneGames13. I wanted to bring this to your attention, as cheating takes away the fun of the game.
