spam creates MEV incentives

[jarret]

I haven't closely followed the discussion since before 2023, but one thing generally missing in the contemporary discussion of 'spam' is the introduction of Miner Extractable Value (MEV) which can corrupt miner incentives.

If, for some reason, someone can extract profit in a secondary way (e.g. frontrun a 'cheap' exchange transaction of non-BTC spam tokens before someone else gets to it), the miners might observe this in the mempool and prefer to confirm one transaction over another (regardless of on-chain-fees) for a more-net-profitable result.
