When you believe someone is cheating the best thing you can do is use the in-game Report Player function: https://www.bungie.net/en/Help/Article/12960 Bungie actively investigates network manipulation and other forms of cheating. We will continue to monitor game performance for people abusing the system and enforce our policies. We regularly address players who we have confirmed are cheating in one form or another. Rest assured that we will continue to do so. Thank you for reporting your experience and helping make Destiny a better community.
