By one person? No. Not understanding how the process works is fine, and that’s where we can clear it up, but this tactic of saying “well, random guy on Reddit says this, so I believe it” is not the way to go.
Player 1 buys gold from an illicit site. Then, they buy an item off the AH from Player 2. They do a couple in-person trade with Players 3 & 4. Then they join a GDKP, where their purchase is split among Players 5-25.
When Blizzard investigates stolen gold, and where that gold went, and who has it now…they find 25 players sharing the gold. Those 25 accounts are flagged for account actions when they are done with the full investigation. Those account actions are done all at once, with a “ban wave” (not a very accurate term, as some accounts may just be suspended, but you get the idea).
So no, one person is not manually actioning 300,000+ accounts. There’s an investigative process that goes into it.
Then, when a player who simply participated in the GDKP run (for example) appeals their action, they look at that player’s actions on their own. Just participating and unknowingly receiving the gold will likely lead to a reduction or immediate reinstatement. Players who knowingly participate and happily take what they know is stolen gold will likely not get a reduction or reinstatement.
Your opinion is irrelevant to the current process. If you think it should change, that’s understandable, and you should leave feedback in the General Discussion Forum. That’s where they gather feedback to consider for the future.
In here, it’s the current policy. Not liking it is irrelevant. There are many things I may not like, but this is Blizzard’s company. I don’t get a say. I only pay to access the game, not make policy decisions.
Your impression of what may be happening is also irrelevant. They are very upfront that automation is used where it makes sense. But that does not involve account actions. A live human decides on account actions, and a live human decides on the outcome of an appeal.
