It seems like the (privacy) requirements for corona tracing apps like the one drafted by the CCC's Linus Neumann seem like a great idea.
Would you have any interest in including such a rating as part of this project @shankari?
I can think about how to implement the rating technically and present it visually in a static website or something, but I can't do the rating itself.
I'm going to ping original author Linus Neumann to see what he thinks about it.
I'm sure we could also find a bunch more volunteers to review the existing projects if we set up a good structure to do it.
