Pretty much. They also sell gold, crafting materials, and items for real money. If you spend a bit of time playing just about any mmo, you’ll see bots and gold sellers all the time.

I'm guessing mining for lootboxes and items. Never underestimate people's ability find money in an absurd waste of resources.

In a lot of mmos, people will farm in game resources and sell them for real money.

Yeah farming or mining whatever you can do.
They sell everything for real money, complete accounts with upgraded characters, or rare items or whatever has value in a game.
