I've seen this before and it's almost certainly developer/transaction construction error. One of the things I make sure to teach about Bitcoin transactions is that you have to send the change back to yourself or it ends up as a fee (tx outputs have only two states, spent and unspent). I suspect that's what happened here. That person made a tx without a change output.

It's not uncommon and has happened quite a few times in Bitcoin history.

Miner: F2Pool (What a nice piece of luck)

According to mempool.space

Overpaid 479867x on fee

Merry Christmas, random miner.

I'd be interested to know!

Well it could be that the miner paid himself to break the link of utxo

I've read on Twitter it could be an agreement with a miner, to get rid of tainted Bitcoins (on a blacklist or something).

Looks like it was PayPal in the end... https://twitter.com/BTC_Archive/status/1701993682990162039

F2pool has offered to return it. https://www.nobsbitcoin.com/f2pool-to-return-20-btc-to-sender/

Whatever custodian or exchange this is, be like:
