They are still in the game even though it is run through the xbox one.
Feel free to report them within the game, any additional images/clips to back up your argument would make your case stronger. There are a lot of players on there, sometimes some slip through the net.
Could you PM me that video? If you post it on here it will get deleted. I always hear about hackers and aim bot and everything else, but every video I ever watch isn't ever anyone hacking. They are just good.
Until I see some hard proof of hacking I won't believe it.
