It's not necessarily a "glitch". It's another way of getting it done. Bungie knows it's there, kinda like a workaround perhaps accidentally on purpose? Drops are the same either way from what I've seen. Done it both ways and the "glitch" way was only seemed slightly easier. I think it's stupid that he felt the need to report them for cheating. There's way more important issues with the game, mainly keeping people connected, for Bungie to be concentrating on right now.
