Well, with that logic, any time someone turns their Xbox off while exiting destiny, or going to the dashboard to quit destiny, is doing network manipulation. They are performing a normal act. Exiting a game, using the provided method to exit. If that's cheating then I guess none of us are allowed to leave the game ever.

Dude bungie has pretty advanced servers. I'm pretty sure they will be able to tell if you've been glitching crota. When VoG came out bungie said they had the ability to monitor players in the raid and could see what they were doing. They've probably already got a script that alerts them when someone disconnects from a crota fight and immediately queues footage of that part of the raid. Remember Activision controls COD and you can get banned for joining a hacked lobby and not leaving.
