On the other hand, I don't see a too ridiculous amount of items in those pics. Biggest is 21, which could be attributed to a mega whale spending $1K on a single scratch, which is, sadly, well within modern whale standards. I've spoken with people in other games who have claimed spending upwards to $10k on a single game. That's addiction tier whaling there, and while we shouldn't take everything we are told for granted, it's quite possible to see people putting that amount of cash in a game. The stolen CC method is also possible. Be it a criminal act or some kid using his dad's CC.
Thing is, while the usual go-to culprit in this game can be duping and hacking, we can't dismiss any other methods either, unless you see someone selling like 500 of a single scratch item.
