This is surprising. I wouldn't have thought a mining pool would offer to do a refund. Though, it's also a good publicity stunt for them.
F2Pool to Return 20 BTC Tx Fee to Owner if It's Claimed Within 3 Days
An unknown Bitcoin network entity paid 19.82 BTC (~$500k) transaction fee to send 0.074 BTC (~$200) - one of the highest fees to date when measured in fiat.

pools have done this before.
its not unprecedented - plenty of mistakes have been made and there's quite a few public cases (bitfinex for example, tho that was eth)
Lmao someone put the ammount to send in the fee box.
Expensive publicity stunt lol. Bitcoin is still a bit wholesome 😌
Integrity!
History is made also by mistakes. #Fail
