Some thoughts on this

(1) - We are discovering more ways to verify past experiences. We think capturing relieving letter is one of the ideas here, but we are open to suggestions.

(2) We absolutely agree with this impression. The core principle of Peerlist is to help build Proof of work. We wanted to start with specific user personas during beta and then cater for others. We started with published content (including public GitHub repos) as it was easier to build with public APIs. We are planning to add more ways to fetch private (non-IP) metadata about the contributions on Peerlist in secure way to help a wider range of users.
