These were PS4 Slim, not PS5.
IIRC they were sitting next to the energy company, tapped illegal electricity, and hidden that fact (the energy company's involvement was under investigation). Criminals don't play fair.
Diablo 3 was one of the earlier games having RMT, and they let community decide to keep or remove it, as it wasn't profitable due to the massive amount of fraud and CS requirement.
Later on, two mobile Blizzard games had RMT and then closed shop: Hearthstone Mercenaries, and Warcraft Rumble. I played both, and fool me once...
