Leaving it alone incentivizes WORSE spam - flooding UTXO set!

The pull request links to a mailinglist post that explains all of this. You're not required to read it, but this "burden of proof" has been more than bet. On the flip side, those who oppose the pull request have not raised a single technically valid argument. And rather than just running Knots, many of them choose to harass developers and frustrate the Github repo.

This is survivorship bias that valid arguments must only exist in their domain where they have the power to censor.
