Duping September 2017?

I have a friend who claims he dupes, he has crowns on all 14 characters and the same dyes, and open a shit ton of keys everyday, and he won't tell me how to do it, anyone have any clue?

*EDIT* I know for a fact he dupes, but how does he do it?

Lucky with white bag drops

There are a couple of dupes atm. Go out and find them.

man i want to know what one is its impossible to find unless u got good hook ups or a friggin genius

Keep this to the dupe discussion stickied thread.

Thanks!
