500 battle pass lvls in 3 days

Running forge on my alt rise account (NA) and I ran into a guy that had a mutant+9, I thought wow this guy bought the battle pass. I then messaged him to ask and was told that if you farm efficiently in forge-11 in your faction corner, and use a stash to transfer loot. You can acquire 20 levels in 1 hour…… you would have to be farming in forge-11 for 8.3 hours, going to round up to 9 hours a day with running back and forth. I knew people like this were out there it just blows my mind that you got it in 3 days, also I got his entire life story without even asking. An unmarried Marine who owns his own company. There’s more but that’s all I will say
