if someone can manage to farm all that in one day from a chest without using any programs/exploits, as boring as it is... then they deserve every credit, and a new title to show off their achievement!
besides you can make MORE credits and XP in a shorter time by farming space missions constantly.
3,237 credits and 5,275 xp every 4 minutes and 3 commendations doing sullest interception.
so by your math, i could also make 1,165,320 credits - 1,897,920 xp - 1,080 fleet commendations. per day farming 24/7. without a single break.
as you can see by doing space missions i would be making TONS more then chest farming, and fleet commendations can be used to buy even more items to sell for more credit gain.
there is really no reason to complain about people who want to farm chests.... it looks like no matter what you do in this game, you will be making credits, some methods are better then others.... and security chests are very low on the list.
