Ok smart one then how did they determine who the first 10 people were who completed kingsfall were? The answer is player data because not all of those groups streamed the raid. Bungie collects player data from every player, this shows raid completions, playlist populations, weapon usage, class usage, etc. if they didnt collect data on players you wouldnt be able to view your games played, k/d and virtually everything else associated with your guardian on this website.
