Luxor may have accepted an out-of-band payment, but the transaction paid a fee of 0 sats: https://mempool.space/tx/0301e0480b374b32851a9462db29dc19fe830a7f7d7a88b81612b9d42099c0ae
Yeah saw it, I really don't know how a tx could be mined without a miner fee, except that was broadcast and mined by the same miner. Otherwise no miner would accept it.

More to the point, the tx wouldn't be mined without a fee because other txs would always outbid it. The mempool is never that empty.
The actual cost of that tx in terms of expected fee revenue has been estimated to be about $2000. Likely that Luxor was paid out of band, and/or did it because it's funny.

Well, if the mempool clears from a mined block it will be almost empty for the next minute or so.
Meaning, the agreement could have been "only mine this block if the total fees that you would get from a normal block is less than 100k sats"
It would take longer but with the current fee market it would have been mined eventually (mempool frequently empty recently) for a cost of $20. Or take 10x on the numbers then $200 but the expected time to mine it is divided by 10.
