I agree regarding the importance of fungability, but not all the way. If a majority of reputation engines only advised rejection of payments as offered by the bottom 1% of ranked teams, then 99% of teams would still experience the fungability expectation. Otherwise, if the reputation engines are too strict, no one would trusts the currency. Too loose, and there is no effective deterence to unsustainable activity. There's an ideal balance to the targeted overall rejection rate among all teams, most likely erring on the side of being too loose (0.5% rejection?), filtering out only the worst of the worst. This targeting to a metric value reminds me of fed actions to indirectly influence the economy, such as with setting interest rates.
