I’m all for trying lots of solutions. Sadly like SEO it’s often a game and a moving target. That’s why I liked the POW concept, at least there is a cost. I think we’ll end up with a fair few strategies working in unison.

One difficultly is shifting from a centralised scoring/identity system, to a per client compute approach. Less data, less power, less compute, less storage, etc. I think we’ll get there however.
