If you suspect cheating or another reportable offense, it's best to use the in-game report system. For those who want to take the extra step by submitting evidence or are unable to report them in-game, you may use the manual tool here: https://help.bungie.net/hc/en-us/articles/360049497451-Report-Suspected-Cheating Posting their names here will accomplish nothing. Bungie's Security Response Team does not use the forums to look for reports as it's against the Code of Conduct to name and shame other users/players here. Reporting in-game or via the aforementioned link will send your reports directly to Bungie for review.
