Assuming its a legit mistake only a major pool would fix this. A small pool would likely keep it.
It was mined by F2Pool
Seems like an human errror but i don't know what to think.
Is there any chance that "human error" was intentionally made as a part of money laundering scheme used by F2Pool? I understand that it is very risky way to cleanse dirty money as the transaction with such enormous fee could be mined by other pool but they might have no option other than to lose money or mine it be themselves.
