They’re just gambling up hundreds of antifreeze scoops to exchange for virtually limitless supplies of cards. It’s not hard, just time-consuming and a little boring unless you really like playing Blackjack (or whatever your game of choice is; I use Blackjack because it’s easy to profit on, but Paper-Rock-Scissors is probably faster for racking up scoops).

To put it in perspective, there’s someone in my bracket this week who has 60+ cards and about as many antifreeze scoops stocked up already. It hasn’t even been 3 hours since the round began yet. If it’s an exploit, it’s definitely in the “anyone can do it” category. Anyone who enjoys virtual gambling for hours on end, anyway.
