Thanks for the clarification. I think by "central bank", the article just meant a non-decentralized currency system.
It's good that you pointed out the possibility for scores to go down in that system, and I assume that would affect the ability of low scoring participants to transact in the system. If that's the case, it makes me doubt the article's strong assertion regarding that example of a reputation currency.
