I fail to see how this cannot be proofed. We have a maximum dosh per day of 150,000 then 500,000 for the weekly. There is a very specific maximum for total dosh earned officially (the Weekly reward having been farmable is something else & if players exploited it to reach over the max potential dosh then they have potentially already earned more than the allotted rewards; ie: no reason to complain).
Vault items cannot be traded or marketed & grind down to a 2 for 1... Oh wait there you go... Yeah, players could exploit this to a small gain by grinding not-so-great Vault rewards & crafting new ones while claiming to have never received a crate. Bogus. Well I too haven't received a crate for my 2 Million mark but I'll continue doing the daily objs just for fun & to see my Vault fill up. **** I had high hopes of getting my crate retroactively rewarded too.
